  [CGP] Support opaque pointers in address mode fold

Rather than inspecting the pointer element type, use the access
type of the load/store/atomicrmw/cmpxchg.

In the process of doing this, simplify the logic by storing the
address + type in MemoryUses, rather than an Instruction + Operand
pair (which was then used to fetch the address).
