ThinLTO: Correctly follow aliasee references when dead stripping.
We were previously handling aliases during dead stripping by adding
the aliased global's "original name" GUID to the worklist. This will
lead to incorrect behaviour if the global has local linkage because
the original name GUID will not correspond to the global's GUID in
the summary.
Because an alias is just another name for the global that it
references, there is no need to mark the referenced global as used,
or to follow references from any other copies of the global. So all
we need to do is to follow references from the aliasee's summary
instead of the alias.

[ThinLTO] For SamplePGO, need to handle ICP targets consistently in thin link
Summary:
SamplePGO indirect call profiles record the target as the original GUID
for statics. The importer had special handling to map to the normal GUID
in that case. The dead global analysis needs the same treatment or
inconsistencies arise, resulting in linker unsats due to some dead
symbols being exported and kept, leaving in references to other dead
symbols that are removed.
This can happen when a SamplePGO profile collected by one binary is used
for a different binary, so the indirect call profiles may not accurately
reflect live targets.

function as they are the potential hoistable candidates.
This patch allows us to hoist instructions to a basic block with >2 successors, as well as deal with infinite loops in a

The solution to this seems to be to determine very early on the entire
set of projects which is enabled. This is complicated by the fact that
there are multiple ways to enable projects, and different tree layouts
(e.g. mono-repo, out of -tree, external, etc). This patch attempts to
centralize all of this into one place, and then updates compiler-rt to
demonstrate as a proof of concept how this can simplify code.

[x86] eliminate unnecessary vector compare for AVX masked store
The masked store instruction only cares about the sign-bit of each mask element,
so the compare s<0 isn't needed.
As noted in PR11210:

Make promoteLoopAccessesToScalars independent of AliasSet [NFC]
Summary:
The current promoteLoopAccessesToScalars method receives an AliasSet, but
the information used is in fact a list of Value*, known to must alias.
Create the list ahead of time to make this method independent of the AliasSet class.
While there is no functionality change, this adds overhead for creating
a set of Value*, when promotion would normally exit earlier.
This is meant to be as a first refactoring step in order to start replacing
AliasSetTracker with MemorySSA.
And while the end goal is to redesign LICM, the first few steps will focus on
adding MemorySSA as an alternative to the AliasSetTracker using most of the
existing functionality.

[X86] Move matching of (and (srl/sra, C), (1<<C) - 1) to BEXTR/BEXTRI instruction to custom isel
Recognizing this pattern during DAG combine hides information about the 'and' and the shift from other combines. I think it should be recognized at isel so its as late as possible. But it can't be done with table based isel because you need to be able to look at both immediates. This patch moves it to custom isel in X86ISelDAGToDAG.cpp.
This does break a couple tests in tbm_patterns because we are now emitting an and_flag node or (cmp and, 0) that we dont' recognize yet. We already had this problem for several other TBM patterns so I think this fine and we can address of them together.
I've also fixed a bug where the combine to BEXTR was preventing us from using a trick of zero extending AH to handle extracts of bits 15:8. We might still want to use BEXTR if it enables load folding. But honestly I hope we narrowed the load instead before got to isel.
I think we should probably also support matching BEXTR from (srl/srl (and mask << C), C). But that should be a different patch.

[LV] Clamp the VF to the trip count
Summary:
When the MaxVectorSize > ConstantTripCount, we should just clamp the
vectorization factor to be the ConstantTripCount.
This vectorizes loops where the TinyTripCountThreshold >= TripCount < MaxVF.
Earlier we were finding the maximum vector width, which could be greater than
the trip count itself. The Loop vectorizer does all the work for generating a
vectorizable loop, but in the end we would always choose the scalar loop (since
the VF > trip count). This allows us to choose the VF keeping in mind the trip
count if available.
This is a fix on top of rL312472.

operations does the actual addition.
- for subtraction, given that ISD::SUBCARRY second result is actually a
borrow, we need to invert the value of the second operand and result before
and after using ARMISD::SUBE. We need to invert the carry result of
ARMISD::SUBE to preserve the semantics.
- given that the generic combiner may lower ISD::ADDCARRY and
ISD::SUBCARRYinto ISD::UADDO and ISD::USUBO we need to update their lowering
as well otherwise i64 operations now would require branches. This implies
updating the corresponding test for unsigned.
- add new combiner to remove the redundant conversions from/to carry flags
to/from boolean values (ARMISD::ADDC (ARMISD::ADDE 0, 0, C), -1) → C

bpf: add " ll" in the LD_IMM64 asmstring
This partially revert previous fix in commit
f5858045aa0b
("bpf: proper print imm64 expression in inst printer").
In that commit, the original suffix "ll" is removed from
LD_IMM64 asmstring. In the customer print method, the "ll"
suffix is printed if the rhs is an immediate. For example,
"r2 = 5ll" => "r2 = 5ll", and "r3 = varll" => "r3 = var".
This has an issue though for assembler. Since assembler
relies on asmstring to do pattern matching, it will not
be able to distiguish between "mov r2, 5" and
"ld_imm64 r2, 5" since both asmstring is "r2 = 5".
In such cases, the assembler uses 64bit load for all
"r = <val>" asm insts.
This patch adds back " ll" suffix for ld_imm64 with one
additional space for "#reg = #global_var" case.

this changes the command line interface of llvm-dwarfdump to match the
one used by the dwarfdump utility shipping on macOS. In addition to
being shorter to type this format also has the advantage of allowing
more than one section to be specified at the same time.

[llvm-cov] Allow hiding instantiation/region coverage from summary tables
Region coverage is difficult to explain without going deep into how
coverage is implemented. Instantiation coverage is easier to explain,
but probably not useful in most cases (templates don't exist in C, and
most C++ code contains relatively few templates).
This patch adds the options "-show-region-summary" and
"-show-instantiation-summary" to allow hiding those columns.
"-show-instantiation-summary" is turned off by default.

WholeProgramDevirt: Add import/export support for targets without absolute symbol constants.
Not all targets support the use of absolute symbols to export
constants. In particular, ARM has a wide variety of constant encodings
that cannot currently be relocated by linkers. So instead of exporting
the constants using symbols, export them directly in the summary.
The values of the constants are left as zeroes on targets that support
symbolic exports.
This may result in more cache misses when targeting those architectures
as a result of arbitrary changes in constant values, but this seems
somewhat unavoidable for now.

As noted in PR34517, the handling of signed div/rem is not on par with
unsigned div/rem. Signed is harder to reason about, but it should be

we use for unsigned: use icmp logic to see if there's a relationship
