To conform to this, you need to fix up the other type-based alias
analysis that's been in the compiler for a long time: MEM_IN_STRUCT_P.
That would be a good thing, because currently -fno-strict-aliasing does
not turn off this alias assumption.
Perhaps MEM_IN_STRUCT_P can be completely removed now there is a general
type alias framework?
