[IR] Add new function attribute nocreateundeforpoison (#164809)
Also add a corresponding intrinsic property that can be used to mark
intrinsics that do not introduce poison, for example simple arithmetic
intrinsics that propagate poison just like a simple arithmetic
instruction.
As a smoke test this patch adds the new property to
llvm.amdgcn.fmul.legacy.
