Summary: PatternState was a mechanism to pass state between the match and rewrite calls of a RewritePattern. With the rise of matchAndRewrite, this class is unused and unnecessary. This revision removes PatternState and simplifies PatternMatchResult to just be a LogicalResult. A future revision will replace all usages of PatternMatchResult/matchSuccess/matchFailure with LogicalResult equivalents.

- rename vars that had inst suffixes (due to ops earlier being
known as insts); other renames for better readability
- drop unnecessary matches in test cases
- iterate without block terminator
- comment/doc updates
- instBodySkew -> affineForOpBodySkew

Note that I'm not asserting this code is correct; I'm simply adding coverage for what's there already. I'm reasonable sure the logic works for existing relaxable instructions, but I wouldn't be suprised if there were incorrect cases for other instructions. (i.e. is it legal to add prefixes to all instructions?)
- libclang_rt.profile should be added when -fcs-profile-generate is on thecommand line.
- OPT_fno_profile_instr_generate was used as a negative for OPT_fprofile_generate. Fix it to use OPT_fno_profile_generate.

TryAnnotateTypeConstraint could annotate a template-id which doesn't end up being a type-constraint,
in which case control flow would incorrectly flow into ParseImplicitInt.
Reenter the loop in this case.
Enable relevant tests for C++20. This required disabling typo-correction during TryAnnotateTypeConstraint
and changing a test case which is broken due to a separate bug (will be reported and handled separately).
Summary:
Run StackSafetyAnalysis at the end of the IR pipeline and annotate
proven safe allocas with !stack-safe metadata. Do not instrument such
allocas in the AArch64StackTagging pass.

This is the second patch in a series of patches to enable basic block
sections support.
This patch adds support for:
* Creating direct jumps at the end of basic blocks that have fall
through instructions.
* New pass, bbsections-prepare, that analyzes placement of basic blocks
in sections.
* Actual placing of a basic block in a unique section with special
handling of exception handling blocks.
* Supports placing a subset of basic blocks in a unique section.
* Support for MIR serialization and deserialization with basic block
sections.

Summary:
This regional op in the QuantOps dialect will be used to wrap
high-precision ops into atomic units for quantization. All the values
used by the internal ops are captured explicitly by the op inputs. The
quantization parameters of the inputs and outputs are stored in the
attributes.

This adds the Arm Optimized Routines (see
https://github.com/ARM-software/optimized-routines) source code under the
the LLVM license. The version of the code provided in this patch is v20.02
of the Arm Optimized Routines project.
This entire contribution is being committed as is even though it does
not currently fit the LLVM libc model and does not follow the LLVM
coding style. In the near future, implementations from this patch will be
moved over to their right place in the LLVM-libc tree. This will be done
over many small patches, all of which will go through the normal LLVM code
review process. See this libc-dev post for the plan:

Skip folds that rely on DataLayout::getTypeAllocSize(). For scalable

Add optional support for opt-in partial reduction cases by providing an optional partial mask to indicate which elements have been extracted for the scalar reduction.
This test case fails due to different handling of weak items between
LLD and LD on PPC. The issue only occurs when the default linker is LLD
and the test case is run on a system where ASLR is enabled.
We were letting G_ANYEXT with a vcc register bank through, which was
incorrect and would select to an invalid copy. Fix this up like G_ZEXT
and G_SEXT. Also drop old code to fixup the non-boolean case in
RegBankSelect. We now have to perform that expansion during selection,
so there's no benefit to doing it during RegBankSelect.
Fixes integers that don't evenly divide to i32 pieces. We should
probably extract some of the code in the legalizer to start handling
argument breakdowns. I'm dissatisfied with the argument lowering's
handling of vectors for example, and we should not be producing the
weird G_EXTRACTs we do now.
Summary: It's possible for an instance of the visual studio debugger
to return a NoneType line number location when stepping during a
debugging session.
This patches teaches DexTer how to handle this particular case without
crashing out.

Summary:
Previously, the range for "->" CXXOperatorCallExpr is the range of the
class object (not including the operator!), e.g. "[[vector_ptr]]->size()".
This patch includes the range of the operator, which fixes the issue
where clangd doesn't go to the overloaded operator "->" definition.

The GDB replay server sanity-checks that every packet it receives
matches what it expects from the serialized packet log. This mechanism
tripped for TestReproducerAttach.py on Linux, because one of the packets
(jModulesInfo) uses run-length encoding. The replay server was comparing
the expanded incoming packet with the unexpanded packet in the log. As a
result, it claimed to have received an unexpected packet, which caused
the test to fail.
This patch addresses that issue by expanding the run-length encoding
before comparing the packets.

I used the implementation for floor instead of round. It also turns
out the OpenCL builtin library wasn't using the round builtin, but
implemented the expanded form.
The nullptr check here was removed in 4ef50a33b1
when I replaced (nearly) all log->Print to LLDB_LOG calls (which automatically
check for this stuff). But it seems this one call escaped my sed call.
Currently working on a test that can cover this code path but we can revert
this until I have found one.
Follow-up for D74433
What the function returns are almost standard BFD names, except that "ELF" is
in uppercase instead of lowercase.
This patch changes "ELF" to "elf" and changes ARM/AArch64 to use their BFD names.
MIPS and PPC64 have endianness differences as well, but this patch does not intend to address them.
Advantages:
* llvm-objdump: the "file format " line matches GNU objdump on ARM/AArch64 objects
* "file format " line can be extracted and fed into llvm-objcopy -O literally.
(https://github.com/ClangBuiltLinux/linux/issues/779 has such a use case)
Affected tools: llvm-readobj, llvm-objdump, llvm-dwarfdump, MCJIT (internal implementation detail, not exposed)
