We were previously just ignoring unreachable, but targets like Darwin want to
keep unreachable instructions as traps.

The LE Power sanitizer bot fails when testing standalone compiler-rt due to
an MSAN test warning introduced by -Wbitwise-instead-of-logical. As this option
along with -Werror is enabled on the bot, the test failure occurs.
This patch updates msan_test.cpp to fix the warning introduced by the
-Wbitwise-instead-of-logical.

In working on D106362 I found that a few more tests were needed. I've
been asked to pre-push the tests for that ticket. This should complete
the tests needed for now.

AArch64StorePairSuppress will prevent the creation of LDP's based on
scheduling info. This shouldn't apply when optimizing for size though,
where the size decrease should be considered more important.

The `fallback` setting for import-std-module is supposed to allow running
expression that require an imported C++ module without causing any regressions
for users (neither in terms of functionality nor performance). This is done by
first trying to normally parse/evaluate an expression and when an error occurred
during this first attempt, we retry with the loaded 'std' module.

When we run into a system with a 'std' module that for some reason doesn't build
or otherwise causes parse errors, then this currently means that the second
parse attempt will overwrite the error diagnostics of the first parse attempt.
Given that the module build errors are outside of the scope of what the user can
influence, it makes more sense to show the errors from the first parse attempt
that are only concerned with the actual user input.

The THEN keyword in the "ELSE IF (test) THEN" statement is useless
syntactically, and to omit it is a common error (at least for me!)
that has poor error recovery.  This patch changes the parser to
cough up a simple "expected 'THEN'" and still recognize the rest of
the IF construct.

In some build environments, the C++ compiler is unable to infer the

This patch is mainly to propogate location attribute from spv.GlobalVariable to llvm.mlir.global.

It also contains three small changes.

1. Remove the restriction on UniformConstant In SPIRVToLLVM.cpp;
2. Remove the errorCheck on relaxedPrecision when deserializering SPIR-V in Deserializer.cpp
3. In SPIRVOps.cpp, let ConstantOp take signedInteger too.

No behavior change.

Note that arg_operands is considered a legacy name.  See
llvm/include/llvm/IR/InstrTypes.h for details.

The test is generated by script, so we don't really need the regname to
be meaniful here.

AIX doesn't support the reg name option, removing it for now so that we
can reuse the CHECKs for AIX triple as well.

This patch introduces a new checker: `alpha.security.cert.env.InvalidPtr`

Checker finds usage of invalidated pointers related to environment.

This is because in that change an implicit widening cast
of the alignment from 32 bit to 64 bit was removed and the
format string expects a 64 bit number.

The size of kmp_depend_info and the number of dependencies are computed multiplying the iterator sizes, which not right.
Now size is computed as:

itersize1*numclausedeps1 + itersize2*numclausedeps2 + ... + itersizeN*numclausedepsN

where itersizeX is the size of the iterator and numclausedepsX the number of dependencies in that depend clause.

In TargetLibraryInfoImpl::isValidProtoForLibFunc we no longer
need the IsSizeTTy lambda function and the SizeTTy object. Instead
we just follow the regular structure of checking for integer types
given an exepected number of bits.

This patch adds a new command line option `openmp-opt-max-iterations`
that controls the maximum number of iterations the attributor will run
for when compiling OpenMP target device code. This patch also adds a
remark to indicate when the attributor failed because it did not run
for enough iterations.

Noticed while investigating the regressions in D110995 - if the RHS element is already zero, then we don't need the corresponding LHS element.

Technically we could also recheck RHS once we have LHS's known zeros, but I haven't seen any missed opportunities from that yet.

This manifested itself as an asan failure in TestMultilineNavigation.py.
