  Log Message:
  -----------
  [NVPTX] properly expand operations that we do not support on v2i32 (#162391)

Follow-up on #153478 and #161715.

v2i32 register class exists mostly to facilitate v2f32's use of integer
registers. There are no actual instructions that can apply to v2i32
directly (except bitwise logical ops). Everything else must be done
elementwise.
