The final piece - using &TARGET_MEM_REF rather than POINTER_PLUS_EXPR to
avoid overflow issues - is clearly a bit of a hack. But otherwise,
keeping around the proper types rather than casting everything to
unsigned int is IMO much less ugly and hackish than what we have now.
Certainly the gimple IL is much less cluttered after the patch than before.
