[DAGCombiner] Add command line options to guard store width reduction
optimizations
As discussed in the thread http://lists.llvm.org/pipermail/llvm-dev/2020-May/141838.html,
some bit field access width can be reduced by ReduceLoadOpStoreWidth, some
can't. If two accesses are very close, and the first access width is reduced,
the second is not. Then the wide load of second access will be stalled for long
time.
This patch add command line options to guard ReduceLoadOpStoreWidth and
ShrinkLoadReplaceStoreWithStore, so users can use them to disable these
store width reduction optimizations.

[analyzer] StdLibraryFunctionsChecker: Add support to lookup types
Summary:
In this patch I am trying to get rid of the `Irrelevant` types from the
signatures of the functions from the standard C library. For that I've
introduced `lookupType()` to be able to lookup arbitrary types in the global
scope. This makes it possible to define the signatures precisely.
Note 1) `fread`'s signature is now fixed to have the proper `FILE *restrict`
type when C99 is the language.
Note 2) There are still existing `Irrelevant` types, but they are all from
POSIX. I am planning to address those together with the missing POSIX functions
(in D79433).

These patterns for i8 and i16 VMLA's were missing. They end up from
legalized vector.reduce.add.v8i16 and vector.reduce.add.v16i8, and
although the instruction works differently (the mul and add are
performed in a higher precision), I believe it is OK because only an
i8/i16 are demanded from them, and so the results will be the same. At
least, they pass any testing I can think to run on them.
There are some tests that end up looking worse, but are quite artificial
due to passing half vector types through a call boundary. I would not

[DAGComb] Do not turn insert_elt into shuffle for single elt vectors.
Currently combineInsertEltToShuffle turns insert_vector_elt into a

would be more efficient than a insert_vector_elt.
Additionally, this fixes a infinite cycle in DAGCombine, where
combineInsertEltToShuffle turns a insert_vector_elt into a shuffle,
which gets turned back into a insert_vector_elt/extract_vector_elt by
a custom AArch64 lowering (in visitVECTOR_SHUFFLE).
Such insert_vector_elt and extract_vector_elt combinations can be
lowered efficiently using mov on AArch64.
There are 2 test changes in arm64-neon-copy.ll: we now use one or two
mov instructions instead of a single zip1. The reason that we need a
second mov in ins1f2 is that we have to move the result to the result
register and is not really related to the DAGCombine fold I think.
But in any case, on most uarchs, mov should be cheaper than zip1. On a

[SCCP] Switch to widen at PHIs, stores and call edges.
Currently SCCP does not widen PHIs, stores or along call edges
(arguments/return values), but on operations that directly extend ranges
(like binary operators).
This means PHIs, stores and call edges are not pessimized by widening
currently, while binary operators are. The main reason for widening
operators initially was that opting-out for certain operations was
more straight-forward in the initial implementation (and it did not
matter too much, as range support initially was only implemented for a
very limited set of operations.
During the discussion in D78391, it was suggested to consider flipping
widening to PHIs, stores and along call edges. After adding support for
tracking the number of range extensions in ValueLattice, limiting the
number of range extensions per value is straight forward.
This patch introduces a MaxWidenSteps option to the MergeOptions,
limiting the number of range extensions per value. For PHIs, it seems
natural allow an extension for each (active) incoming value plus 1. For
the other cases, a arbitrary limit of 10 has been chosen initially. It would
potentially make sense to set it depending on the users of a
function/global, but that still needs investigating. This potentially
leads to more state-changes and longer compile-times.

[clangd] locateMacroAt handles patched macros
Summary: Depends on D79992.
This patch changes locateMacroAt to perform #line directive substitution
for macro identifier locations.
We first check whether a location is inside a file included through
built-in header. If so we check whether line directive maps it back to
the main file, and afterwards use TokenBuffers to find exact location of
the identifier on the line.
Instead of performing the mapping in locateMacroAt, we could also store
a mapping inside the ParsedAST whenever we use a patched preamble. But
that would imply adding more responsibility to ParsedAST and paying for
the mapping even when it is not going to be used.
====
Go-To-Definition:
Later on these locations are used for serving go-to-definition requests,
this enables jumping to definition inside the preamble section in
presence of patched macros.
=====
Go-To-Refs:
Macro references in main file are collected separetely and stored as a
map from macro's symbol id to reference ranges. Those ranges are
computed inside PPCallbacks, hence we don't have access to TokenBuffer.
In presence of preamble patch, any reference to a macro inside the
preamble section will unfortunately have the wrong range. They'll point
into the patch rather than the main file. Hence during findReferences,
we won't get any ranges reported for those.
Fixing those requires:
- Lexing the preamble section to figure out "real range" of a patched
macro definition
- Postponing range/location calculations until a later step in which we
have access to tokenbuffers.
This patch trades some accuracy in favor of code complexity. We don't do
any patching for references inside the preamble patch but get any
reference inside the main file for free.

[lldb] Make "inline" tests more configurable
Summary:
This patch adds two new arguments to the MakeInlineTest function. The
main motivation is a follow-up patch I'm preparing, but they seem
generally useful.
The first argument allows the user to specify the "build dictionary".
With this argument one can avoid the need to provide a custom Makefile
if all he needs is to override a couple of make variables. This hooks in
neatly into the existing dictionary support for non-inline tests.
The second argument specifies the name of the test. This could be used
to provide better names to the generated test classes, but it's mainly
useful in conjuction with the first argument: now that we can specify a
custom build dictionary, it may sometimes make sense to run the same
test twice with different build configurations. To achieve that, we need
to give the two tests different names, and this argument achieves that.
The usage of the arguments is demonstrated via TestBasicEntryValues.py.

New intrinsic @llvm.get.active.lane.mask()
This is split off from D79100 and:
- adds a intrinsic description/definition for @llvm.get.active.lane.mask(), and
- describe its semantics in LangRef.
As described (in more detail) in its LangRef section, it is semantically
equivalent to an icmp with the vector induction variable and the back-edge
taken count, and generates a mask of active/inactive vector lanes.
It will have several use cases. First, it will be used by the
ExpandVectorPredication pass for the VP intrinsics, to expand VP intrinsics for
scalable vectors on targets that do not support the `%evl` parameter, see
D78203.
Also, this is part of, and essential for our ARM MVE tail-predication story:
- this intrinsic will be emitted by the LoopVectorizer in D79100, when
the scalar epilogue is tail-folded into the vector body. This new intrinsic
will generate the predicate for the masked loads/stores, and it takes the
back-edge taken count as an argument. The back-edge taken count represents the
number of elements processed by the loop, which we need to setup MVE
tail-predication.
- Emitting the intrinsic is controlled by a new TTI hook, see D80597.
- We pick up this new intrinsic in an ARM MVETailPredication backend pass, see
D79175, and convert it to a MVE target specific intrinsic/instruction to
create a tail-predicated loop.

[WebAssembly] Fix a bug in finding matching EH pad
Summary:
`getMatchingEHPad()` in LateEHPrepare is a function to find the nearest
EH pad that dominates the given instruction. This intends to be
lightweight so it does not use full WebAssemblyException scope analysis
or dominator analysis. It simply does backward BFS to its predecessors
and stops at the first EH pad each search path encounters. All search
should end up at the same EH pad, and if not, it returns null.
But it didn't take into account that when there are inner scopes within
the current scope, some path in BFS can hit an inner EH pad first. For
example, in the given diagram, `Inst` belongs to the outer scope and
`getMathingEHPad()` should return 'EHPad 1', but some search path can go
into the inner scope and end up with 'EHPad 2'. The search will return
null because different paths end up with different EH pads.
```
--- EHPad 1 ---
| - EHPad 2 - |
| | | |
| ----------- |
| Inst |
---------------
```
So far this was OK because we haven't tested a case in which a given
instruction is far from its EH pad. Also, this bug does not happen when
the inner EH scope is a cleanup scope, because a cleanup scope ends with
a `cleanupret` whose successor is an EH pad, so the search encounters
that EH pad first before going into the child scope. But this can happen
when the child scope is a catch scope that ends with `catchret`. So this
patch, when doing backward BFS, does not search predecessors that ends
with `catchret`. Because `catchret`s are replaced with `br`s during this
pass, this records BBs that have `catchret`s in the beginning, before
doing any other transformations.

Summary:
One of the things `removeUnnecessaryInstrs()` in CFGStackify does is to
remove an unnecessary unconditinal branch before an EH pad. When there
is an unconditional branch right before a catch instruction and it
branches to the end of `end_try` marker, we don't need the branch,
because it there is no exception, the control flow transfers to
that point anyway.
```
bb0:
try
...
br bb2 <- Not necessary
bb1:
catch
...

This applies when we have a conditional branch followed by an
unconditional one, in which case we should only remove the unconditional
branch. For example:
```
bb0:
try
...
br_if someplace_else
br bb2 <- Not necessary
bb1:

But `TargetInstrInfo::removeBranch` we used removed all existing

GlobalISel: Work on improving stock set of legality predicates
I get confused by a lot of the predicate names here, since I would
assume they apply to vectors as well. Rename to reflect they only
apply to scalars.
Also add a few predicates AMDGPU uses that should be generally useful.
Also add any() to complement all. I've wanted to use this a few times
but then worked around it not being there.

[X86] Fix a nullptr dereference in X86Subtarget::classifyLocalReference when compiling with -mcmodel=medium -fpic and using a constant pool
LowerConstantPool passes a nullptr into classifyLocalReference. The medium code model handling for PIC will try to deference it using isa. This patch switches to isa_and_nonnull.

Run Coverage pass before other *San passes under new pass manager, round 2
Summary:
This was attempted once before in https://reviews.llvm.org/D79698, but
was reverted due to the coverage pass running in the wrong part of the
pipeline. This commit puts it in the same place as the other sanitizers.
This changes PassBuilder.OptimizerLastEPCallbacks to work on a
ModulePassManager instead of a FunctionPassManager. That is because
SanitizerCoverage cannot (easily) be split into a module pass and a
function pass like some of the other sanitizers since in its current
implementation it conditionally inserts module constructors based on
whether or not it successfully modified functions.
This fixes compiler-rt/test/msan/coverage-levels.cpp under the new pass
manager (last check-msan test).
Currently sanitizers + LTO don't work together under the new pass
manager, so I removed tests that checked that this combination works for
sancov.

[lld][WebAssembly] Convert some lld tests to assembly
When we originally wrote these tests we didn't have a stable and
fleshed out assembly format. Now we do so we should prefer that
over llvm ir for lld tests to avoid including more part of llvm
than necessary in order to run the test.
This change converts just 30 out of about 130 test files. More to
come when I have some more time.
