The LoongArch ELF psABI document has changed location and versioning
scheme; this revision is v2.10 in the old scheme. Notably this revision
brings initial capability of linker relaxation to LoongArch.

In https://reviews.llvm.org/D147812 I created
`BalancedPartitioningTest.cpp` and inadvertently drastically increased the
number of files needed to compile `SupportTests`. Instead lets move the
`BPFunctionNode` test to `unittests/ProfileData` so we can remove the
extra dependency.

It's possible that both multiplicands are being negated. This won't
change the opcode, but we can delete the two negates. Allow this
case to get through negateFMAOpcode.
I think D152260 will also fix this test case, but in the future
it may be possible for an fneg to appear after we've already converted
to RISCVISD opcodes in which case D152260 won't help.

On Darwin, we do not want to show the BuildId appended at the end of stack
frames in Sanitizers. The BuildId/UUID can be seen by using the
print_module_map=1 sanitizer option.

This patch skips both `test_completion_target_create_from_root_dir`
introduced in `e896612` and `target-label.test` introduced in `1e82b20`
since I don't have a windows machine to try to accomodate the filesystem
path style differences for these tests to pass.

Fix debug printing, making it easier to compare two debug logs side by side:
- `BinaryFunction::addRelocation`: print function name instead of `this` ptr,
- `DataAggregator::doTrace`: remove duplicated function name.

CUDA-12 no longer supports 32-bit compilation.
Tests agnostic to 32/64 compilation mode are switched to use nvptx64.
Tests that do care about it have 32-bit ptxas compilation disabled with cuda-12+.

AMDGPU has native instructions and target intrinsics for this, but
these really should be subject to legalization and generic
optimizations. This will enable legalization of f16->f32 on targets
without f16 support.
Implement a somewhat horrible inline expansion for targets without
libcall support. This could be better if we could introduce control
flow (GlobalISel version not yet implemented). Support for strictfp
legalization is less complete but works for the simple cases.
This simplifies the usage of `__less` by making the class not depend on the types compared, but instead the `operator()`. We can't remove the template completely because we explicitly instantiate `std::__sort` with `__less<T>`.

Parametrize SampleProfileInference and SampleProfileLoaderBaseImpl by function
type (Function/MachineFunction) instead of block type
(BasicBlock/MachineBasicBlock). Move out specializations to appropriate
locations.
This change makes it possible to use GraphTraits instead of a custom TypeMap and
make SampleProfileInference not dependent on LLVM types, paving the way for
generalizing SampleProfileInference interfaces to BOLT IR types
(BinaryFunction/BinaryBasicBlock) in stale profile matching (D144500).

Back in 2020 [1], we went very close to enabling Filesystem on MSVC
by disabling int128_t, but decided to wait because MSVC support
for int128_t was supposed to come shortly after. Since it's not
there yet, I propose turning off int128_t support by default on MSVC.
This will make <filesystem> available by default on MSVC, and most
importantly will open the possibility for changing
LIBCXX_ENABLE_FILESYSTEM to mean "the system doesn't have support
for a filesystem" instead of simply "don't build the std::filesystem
library", which is what I'm really after with this change.
In a way, this is a resurection of D91139.

Instead of guarding header tests using #ifdefs inside the tests,
use Lit markup to mark all the tests as unsupported. This is simpler
but also provides better feedback about which tests are being run
when running the test suite.

There are some new cases if the division is `exact`:
1: If `TZ(LHS) == TZ(RHS)` then the result is always Odd
2: If `TZ(LHS) > TZ(RHS)` then the `TZ(LHS)-TZ(RHS)` bits of the
result are zero.

As well, return zero in known poison cases to be consistent rather

It seems consistent to always return zero for known poison rather than
varying the value. We do the same elsewhere.

Chronically misspelled 'denominator' as 'denuminator' and a few other
cases.
On the logic side, no longer require `RHS` to be strictly positive in
`sdiv`. This in turn means we need to handle a possible zero `denom`
in the APInt division.
