  Log Message:
  -----------
  [SimplifyLibCalls] Retain attributes added by Builder.CreateMem*

This currently does not make much of a difference (only one tests is
affected), but it is helpful e.g. for the out-of-tree CHERI target where
Builder.CreateMemCpy() can add attributes other than parameter alignment.
