[Coroutines] Part 5: Add CGSCC restart trigger
Summary:
CoroSplit pass processes the coroutine twice. First, it lets it go through
complete IPO optimization pipeline as a single function. It forces restart
of the pipeline by inserting an indirect call to an empty function "coro.devirt.trigger"
which is devirtualized by CoroElide pass that triggers a restart of the pipeline by CGPassManager.
(In later patches, when CoroSplit pass sees the same coroutine the second time, it splits it up,
adds coroutine subfunctions to the SCC to be processed by IPO pipeline.)
Documentation and overview is here: http://llvm.org/docs/Coroutines.html.
Upstreaming sequence (rough plan)
1.Add documentation. (https://reviews.llvm.org/D22603)
2.Add coroutine intrinsics. (https://reviews.llvm.org/D22659)

c) Do devirtualization (https://reviews.llvm.org/D23229)

[ADT] Make the triple test 1000x faster through more focused test cases.
The current approach isn't a long-term viable pattern. Given the set of
architectures A, vendors V, operating systems O, and environments E, it
does |A| * |V| * |O| * |E| * 4! tests. As LLVM grows, this test keeps
getting slower, despite my working very hard to make it get some
"optimizations" even in -O0 builds in order to lower the constant
factors. Fundamentally, we're doing an unreasonable amount of work.i
Looking at the specific thing being tested -- the goal seems very
clearly to be testing the *permutations*, not the *combinations*. The
combinations are driving up the complexity much more than anything else.
Instead, test every possible value for a given triple entry in every
permutation of *some* triple. This really seems to cover the core goal
of the test. Every single possible triple component is tested in every
position. But because we keep the rest of the triple constant, it does
so in a dramatically more scalable amount of time. With this model we do
(|A| + |V| + |O| + |E|) * 4! tests.
For me on a debug build, this goes from running for 19 seconds to 19
milliseconds, or a 1000x improvement. This makes a world of difference
for the critical path of 'ninja check-llvm' and other extremely common
workflows.
Thanks to Renato, Dean, and David for the helpful review comments and
helping me refine the explanation of the change.

CodeGen: If Convert blocks that would form a diamond when tail-merged.
The following function currently relies on tail-merging for if
conversion to succeed. The common tail of cond_true and cond_false is
extracted, and this then forms a diamond pattern that can be
successfully if converted.
If this block does not get extracted, either because tail-merging is
disabled or the threshold is higher, we should still recognize this
pattern and if-convert it.

Resubmit "Make YAML support SmallVector"
This resubmits
a3770391c5fb64108d565e12f61dd77ce71b5b4f,
which was reverted due to breakages on non-Windows machines.
Due to differences in template instantiation rules on Microsoft
and non-Microsoft platforms, a member access restriction was
triggering on non-Microsoft compilers. Previously, a friend
declaration for std::vector<> had been introduced into the
DebugMap class to make the member access restriction pass,
but the introduction of support for SmallVector<> meant that
an additional friend declaration would need to be added.
This didn't really make a lot of sense since the user of the
macro is probably only using one type (SmallVector<>, vector<>,
etc) and we could in theory add support for even more types
to this macro in the future (e.g. std::deque), so rather than
add another friend declaration, I just made the type being
referenced a public nested typedef instead of a private nested
typedef.

[CodeView] Decouple record deserialization from visitor dispatch.
Until now, our use case for the visitor has been to take a stream of bytes
representing a type stream, deserialize the records in sequence, and do
something with them, where "something" is determined by how the user
implements a particular set of callbacks on an abstract class.
For actually writing PDBs, however, we want to do the reverse. We have
some kind of description of the list of records in their in-memory format,
and we want to process each one. Perhaps by serializing them to a byte
stream, or perhaps by converting them from one description format (Yaml)
to another (in-memory representation).
This was difficult in the current model because deserialization and
invoking the callbacks were tightly coupled.
With this patch we change this so that TypeDeserializer is itself an
implementation of the particular set of callbacks. This decouples
deserialization from the iteration over a list of records and invocation
of the callbacks. TypeDeserializer is initialized with another
implementation of the callback interface, so that upon deserialization it
can pass the deserialized record through to the next set of callbacks. In
a sense this is like an implementation of the Decorator design pattern,
where the Deserializer is a decorator.
This will be useful for writing Pdbs from yaml, where we have a
description of the type records in Yaml format. In this case, the visitor
implementation would have each visitation callback method implemented in
such a way as to extract the proper set of fields from the Yaml, and it
could maintain state that builds up a list of these records. Finally at
the end we can pass this information through to another set of callbacks
which serializes them into a byte stream.

No test-case yet: This bug was uncovered during work on an upcoming patch for
weak symbol support and the testcase for that feature will implicitly test for
correct behavior here.

Add the first of what will be a long line of additional error checks for invalid Mach-O files.
This is where an LC_SEGMENT load command has a fileoff field that
extends past the end of the file.
Also fix llvm-nm and llvm-size to remove the errorToErrorCode() call so error messages are printed.
And needed to update a few test cases now that they do print the error messages just a
bit differently.

[PowerPC] Wrong fast-isel codegen for VSX floating-point loads
There were two locations where fast-isel would generate a LFD instruction
with a target register class VSFRC instead of F8RC when VSX was enabled.
This can ccause invalid registers to be used in certain cases, like:
lfd 36, ...
instead of using a VSX load instruction. The wrong register number gets
silently truncated, causing invalid code to be generated.
The first place is PPCFastISel::PPCEmitLoad, which had multiple problems:
1.) The IsVSSRC and IsVSFRC flags are not initialized correctly, since they
are computed from resultReg, which is still zero at this point in many cases.
Fixed by changing the helper routines to operate on a register class instead
of a register and passing in UseRC.
2.) Even with this fixed, Is64VSXLoad is still wrong due to a typo:
bool Is32VSXLoad = IsVSSRC && Opc == PPC::LFS;
bool Is64VSXLoad = IsVSSRC && Opc == PPC::LFD;
The second line needs to use isVSFRC (like PPCEmitStore does).
3.) Once both the above are fixed, we're now generating a VSX instruction --
but an incorrect one, since generation of an indexed instruction with null
index is wrong. Fixed by copying the code handling the same issue in
PPCEmitStore.
The second place is PPCFastISel::PPCMaterializeFP, where we would emit an
LFD to load a constant from the literal pool, and use the wrong result
register class. Fixed by hardcoding a F8RC class even on systems
supporting VSX.

[SimplifyCFG] Make range reduction code deterministic.
This generated IR based on the order of evaluation, which is different
between GCC and Clang. With that in mind you get bootstrap miscompares
if you compare a Clang built with GCC-built Clang vs. Clang built with
Clang-built Clang. Diagnosing that made my head hurt.
This also reverts commit r277337, which "fixed" the test case.
