[DSE] Support opaque pointers

For the start shortening optimization, always use a i8 type for
the GEP, as it is a raw offset calculation.

Handling of non-i8* memset/memcpy arguments requires insertion
of casts. These cases were previously miscompiled, as the offset
calculation was performed on the wrong type.
