  -----------
  InferAddressSpaces: Improve handling of instructions with multiple pointer uses

The use list iteration worked correctly for the load and store case. The atomic
instructions happen to have the pointer value as the last visited operand, but we
rejected the instruction as simple after the first encountered use.

Ignore the use list for the recognized load/store/atomic instructions, and just
try to directly replace the known pointer use.
