InstCombine: Optimize GEP's involving ptrtoint better
We supported transforming:
(gep i8* X, -(ptrtoint Y))
to:
(inttoptr (sub (ptrtoint X), (ptrtoint Y)))
However, this only fired if 'X' had type i8*. Generalize this to
support various types of different sizes. This results in much better
CodeGen, especially for pointers to packed structs.
