  Log Message:
  -----------
  [NVPTX] Aggressively try to replace image handles with references (#119730)

Even in cases where handles are supported, references are still
preferable for performance. This is because, a ref uses one
less register and can avoid the handle creating code associated with
taking the address of a tex/surf/sampler.
