When we use mask compare intrinsics under strict FP option, the masked
elements shouldn't raise any exception. So, we cann't replace the
intrinsic with a full compare + "and" operation.

This patch refactors the DWARF section dumpers. When dumping a DWARF
section, if the DWARF parser fails to parse the section, we will dump it
as a raw content section. This patch also fixes a bug in
DWARFYAML::Data::isEmpty(). Finally, a test case that tests dumping the
__debug_aranges section is added.

Replace the `ident_t` handling in Clang with the methods offered by the
OMPIRBuilder. This cuts down on the clang code as well as the
differences between the two, making further transitions easier. Tests
have changed but there should not be a real functional change. The most
interesting difference is probably that we stop generating local ident_t
allocations for now and just use globals. Given that this happens only
with debug info, the location part of the `ident_t` is probably bigger
than the test anyway. As the location part is already a global, we can
avoid the allocation, memcpy, and store in favor of a constant global
that is slightly bigger. This can be revisited if there are
complications.

This changes adds infrastructure to distribute the loops generated in
Linalg to processors at the time of generation. This addresses use
case where the instantiation of loop is done just to distribute
them. The option to distribute is added to TilingOptions for now and
will allow specifying the distribution as a transformation option,
just like tiling and promotion are specified as options.

Use TE SMC instead of TC SMC in large code model mode,
so that large code model TOC entries could get placed after all

In cases where MachineOutliner candidates either are:
* noreturn
* have calls with no available LR or free regs
* Don't use SP
we can end up hitting stack fixup code for the caller and the callee for
a FrameID of MachineOutlinerDefault. This triggers the assert:
`assert(OF.FrameConstructionID != MachineOutlinerDefault &&
"Can only fix up stack references once");`
in AArch64InstrInfo.cpp. This assert exists for now because a lot of the
fixup code is not tested to handle fixing up more than once and needs
some better checks and enhancements to avoid potentially generating
illegal code.
I've filed a Bugzilla report to track this until these cases are handled
by the AArch64 MachineOutliner: https://bugs.llvm.org/show_bug.cgi?id=46767
This diff detects cases that will cause these multiple stack fixups and
prune the Candidates from `RepeatedSequenceLocs`.

for invoke instructions.
We see a warning of "No debug information found in function foo: Function
profile not used" in a case. The function foo is called by an invoke
instruction. It has no debug information because it has attribute((nodebug))
in the definition. It shouldn't have profile instance in the sample profile
but compiler thinks it does, that turns out to be a compiler bug in
findCalleeFunctionSamples. The bug is exposed when sample-profile-merge-inlinee
is enabled recently.
Currently in findCalleeFunctionSamples, CalleeName is unset and is empty for
invoke instruction. For empty CalleeName, findFunctionSamplesAt will treat
the call as an indirect call and will return any inline instance profile at
the same location as the instruction. That leads to a wrong profile being
returned to function foo.
The patch set CalleeName when the instruction is an invoke.

The former function is particularly optimized for exactly the
use case we're interested in: an all-zero buffer.
This reduces the overhead of calling this function some 80% or
more. This is particularly for instrumenting code heavy with
string processing functions, like grep. An invocation of grep
with the pattern '[aeiou]k[aeiou]' has its runtime reduced by
~75% with this patch

The bundle shall be undone by VirtRegRewriter::expandCopyBundle(),

This can fold the immediate into the physical destination, but this
should not look for further users of the register. Fixes regression
introduced by 766cb615a3.
This patch adds the missing information to the LF_BUILDINFO record, which allows for rebuilding a .CPP without any external dependency but the .OBJ itself (other than the compiler).
Some external tools that we are using (Recode, Live++) are extracting the information to reproduce a build without any knowledge of the build system. The LF_BUILDINFO stores a full path to the compiler, the PWD (CWD at program startup), a relative or absolute path to the TU, and the full CC1 command line. The command line needs to be freestanding (not depend on any environment variables). In the same way, MSVC doesn't store the provided command-line, but an expanded version (somehow their equivalent of CC1) which is also freestanding.
For more information see PR36198 and D43002.

X86 is the only user of this interface in tree. Previously the
X86 pass would loop over operands looking for one undef operand for
the pass to fix. But there could theoretically be multiple operands
to fix. So it makes more sense for the pass to do the looping and
ask the target if an operand needs to be fixed.
