Arthur Eubanks c19d7f8af0 [CallPromotion] Check for inalloca/byval mismatch ...

Previously we would allow promotion even if the byval/inalloca
attributes on the call and the callee didn't match.

It's ok if the byval/inalloca types aren't the same. For example, LTO
importing may rename types.

Fixes PR51397.
