[msan] Add test cases for vector shadow track origins bug (#97611)
These test cases demonstrate a bug in MSan (vector shadow is not always
converted to scalar before zext) that will shortly be fixed in
https://github.com/llvm/llvm-project/pull/96722
The bug is not architecture-specific; we provide both x86 and Arm NEON
test cases.
Since the test cases will crash the compiler (unless it is a release
build), they are marked as UNSUPPORTED.
The buggy codepath is nested inside 'if
(instrumentWithCalls(ConvertedShadow)'. To keep the test cases small, we
set -msan-instrumentation-with-call-threshold=0, though we have observed
this bug in the real world with default settings.
