  Log Message:
  -----------
  [NVPTX] Allow directly storing immediates to improve readability (#145552)

Allow directly storing an immediate instead of requiring that it first
be moved into a register. This makes for more compact and readable PTX.
An approach similar to this (using a ComplexPattern) this could be used
for most PTX instructions to avoid the need for `_[ri]+` variants and
boiler-plate.
