  -----------
  [IR][AutoUpgrade] Drop alignment from non-pointer parameters and returns

This is a follow-up of D102201. After some discussion, it is a better idea
to upgrade all invalid uses of alignment attributes on function return
values and parameters, not just limited to void function return types.
