I mean, why do we have to watch for type mismatches and fix them instead of creating the correct type in the first place?
There is `getPointerType(RetQT)` just above, shouldn't it be something like `getPointerType(RetQT, <correct address space>)`?
Or RetQT should have had the correct address space, but for some reason it was lost?
