> Yeah, that sounds reasonable.

There is a further subtlety in the second temp allocation when the expression 
doesn't use the alias set of its type.  In that case, we cannot pass the type 
to set_mem_attributes.  In fact, since assign_stack_temp_for_type already 
calls the appropriate set_mem_* routines, the best thing to do might be to 
remove the call to set_mem_attributes altogether in that case.
