Detailed Description

Provide an iterator that walks defs, giving both the memory access, and the current pointer location, updating the pointer location as it changes due to phi node translation.

This iterator, while somewhat specialized, is what most clients actually want when walking upwards through MemorySSA def chains. It takes a pair of <MemoryAccess,MemoryLocation>, and walks defs, properly translating the memory location through phi nodes for the user.
