  Log Message:
  -----------
  [InferAddrSpace] Teach to handle assumed address space.

- In certain cases, a generic pointer could be assumed as a pointer to
  the global memory space or other spaces. With a dedicated target hook
  to query that address space from a given value, infer-address-space
  pass could infer and propagate that to all its users.
