  -----------
  [NVPTX] Further cleanup call isel (#146411)

This change continues rewriting and cleanup around DAG ISel for
formal-arguments, return values, and function calls. This causes some
incidental changes, mostly to instruction ordering and register naming
but also a couple improvements caused by using scalar types earlier in
the lowering.
