[OpenMP] libomp: Handle implicit conversion warnings
This patch partially prepares the runtime source code to be built with
-Wconversion, which should trigger warnings if any implicit conversions
can possibly change a value. For builds done with icc or gcc, all such
warnings are handled in this patch. clang gives a much longer list of
warnings, particularly for sign conversions, which the other compilers
don't report. The -Wconversion flag is commented into cmake files, but
I'm not going to turn it on. If someone thinks it is important, and wants
to fix all the clang warnings, they are welcome to.
Types of changes made here involve either improving the consistency of types
used so that no conversion is needed, or else performing careful explicit
conversions, when we're sure a problem won't arise.
Patch is a combination of changes by Terry Wilmarth and Johnny Peyton.

The matching for intrinsic names is forgiving about types in the
name being absent or wrong. Once the intrinsic is parsed its
name will remangled to include the real types.
This commit fixes the names to have at least enough correct types
so that the name used in the test is a prefix of the canonical name.
The big missing part is the type for the VL parameter which changes
size between rv32 and rv64.
While I was in here I noticed that we were missing some tests for
double on rv32 so I fixed that by copying from rv64 and fixing up
the VL argument type.

Fix DRR pattern when attributes and operands are interleaved and a dag subtree appears in the rewrite
This fixes an incorrect fatal error in TableGen. This code probably comes
from before attributes were allowed to interleave with operands in ODS.

[MLIR] Make ComplexType buildable if its element type is buildable
If a ComplexType's element type is buildable, then that ComplexType should be
buildable. This is accomplished by the introduction of a new ODS class called
`SameBuildabilityAs`. This can be used by other types that are conditionally
buildable.

Use "return std::move(AsmStreamer);" instead of "return AsmStreamer;" in
LVMTargetMachine::createMCStreamer. Unlike Clang, GCC seems having trouble
inserting a implicit lvalue->rvalue conversion.

[llvm-elfabi] Add flag to preserve timestamp when output is the same
This change adds '--write-if-changed' flag to llvm-elfabi tool. When
enabled, llvm-elfabi will not overwrite the existing file if the
content of the file will not be changed, which preserves the
