Summary:
The masked load / store LLVM intrinsics take an argument for the
alignment. If the user is pessimistic about alignment they can provide a
value of `1` for an unaligned load. This patch updates infer-alignment
to
increase the alignment value of the alignment argument if it is known
greater than the provided one.
Ignoring the gather / scatter versions for now since they contain many
pointers.
