[x86] these aren't the undefs you're looking for (PR32176) x86 has undef SSE/AVX intrinsics that should represent a bogus register operand. This is not the same as LLVM's undef value which can take on multiple bit patterns. There are better solutions / follow-ups to this discussed here: https://bugs.llvm.org/show_bug.cgi?id=32176 ...but this should prevent miscompiles with a one-line code change.
