  Log Message:
  -----------
  [AArch64] Protect against mismatching sizes in UMOV combine. (#202116)

This fixes an issue from #199139 where a later revision was not checking
the connection between the size of the UMOV and the size of the store.
This adds a check, based on the register sizes and the memory size from
the MMO.
