Only functions with floating-point return type accepts fast-math flags.
When adding such flags to function returning integer, we'll see a crash,
because there's still an undeleted value referencing the argument. This
patch manually removes the temporary instruction when error occurs.

This patch is a follow up on https://reviews.llvm.org/D81627.
In addition to default -fno-gpu-rdc case, this patches let
HIP toolchain not use llvm-link/opt/llc to link device code
for -fgpu-rdc case. Instead, uses standard lto.
This will eliminate some redundant optimizations and speed
up the compilation/linking.

Summary:
Normally, the Origin is passed over TLS, which seems like it introduces unnecessary overhead. It's in the (extremely) cold path though, so the only overhead is in code size.
But with eager-checks, calls to __msan_warning functions are extremely common, so this becomes a useful optimization.
This can save ~5% code size.

MSVC uses lit for STL testing to run both the libcxx tests and our "native" suite of tests which has feature requirements that are not parsed from the test content. For consistency, the change treats the `unsupported` and `xfails` `Test` properties similarly to `requires`.

It's possible to end up with a zext or something in the way of a G_CONSTANT,
even pre-legalization. This can happen with memsets.
e.g.

To make sure we can catch these cases, use `getConstantVRegValWithLookThrough`
instead of `mi_match`.

Summary: FileLineColLoc allows the column and line to be zero to represent unknown column and/or unknown line/column information. However, SourceMgr::FindLocForLineAndColumn treats line 0 and col 0 valid and pointing to the first line and col, respectively. To adapt this mismatch in semantics, we explicitly check line/col being zeros in SourceMgrDiagnosticHandler::convertLocToSMLoc

This removes the need to pass std::array of Addresses to getFunction,
which were overwritten in the function.
This allows for passing a lambda to addDynamicallyLegalDialect without needing to explicit wrap with Optional<DynamicLegalityCallbackFn>.

It is quite common for the same type to be converted many types throughout the conversion process, and there isn't any good reason why we aren't caching that result. Especially given that we currently use identity conversion to signify legality. This revision also adds a few additional helpers to TypeConverter.

Currently HIP toolchain calls clang to emit bitcode then calls opt/llc for device compilation for the default -fno-gpu-rdc
case, which is unnecessary since clang is able to compile a single source file to ISA.
This patch fixes the HIP action builder and toolchain so that the default -fno-gpu-rdc can be done like a canonical
toolchain, i.e. one clang -cc1 invocation to compile source code to ISA.
This can avoid unnecessary processes to speed up the compilation, and avoid redundant LLVM passes which are
performed in clang -cc1 and opt.

This revision replaces MatmulOp, now that DRR rules have been dropped.
This revision also fixes minor parsing bugs and a plugs a few holes to get e2e paths working (e.g. library call emission).
During the replacement the i32 version had to be dropped because only the EDSC operators +, *, etc support type inference.
Deciding on a type-polymorphic behavior, and implementing it, is left for future work.

The commit was reverted in 43c4afb56f because it broke the Windows to
Linux cross-compilation build bots. The issue turned out to be that the
bots were setting the LIBCXX_EXECUTOR incorrectly. This has been fixed
now and verified with the bot owners.
Note that this is only a partial re-application of the commit, since
non-problematic parts of the commits have already been re-applied earlier.
The initial intent was to organize ML stuff in its own directory, but
it turns out that conflicts with llvm component layering policies: it
is not a component, because subsequent changes want to rely on other
analyses, which would create a cycle; and we don't have a reliable,
cross-platform mechanism to compile files in a subdirectory, and fit in
the existing LLVM build structure.
This change moves the files into Analysis, and subsequent changes will
leverage conditional compilation for those that have optional
dependencies.

The promotion machinery in CGP moves instructions retaining
debug locations. When the transformation is local, this is mostly
correct, but when instructions are moved cross-BBs, this is not
always true and causes jumpiness in line tables. This is the first
of a series of commits. sext(s) and zext(s) need to be treated
similarly.

As suggested in D81472, the load/store intrinsics' pointer arguments can
be marked as nocapture and all matrix intrinsics as nosync.
This also re-flows the intrinsic definitions, to make them a little more

This is intended to avoid programming mistake where a temporary OpOperand is
created, for example:
for (OpOperand user : result.getUsers()) {
It can be confusing for the user, in particular since in MLIR most classes are intended to
be copied around by value while they have reference semantics.
