  AMDGPU/GlobalISel: Handle atomic sextload and zextload

Atomic loads are handled differently from the DAG, and have separate opcodes
and explicit control over the extensions, like ordinary loads. Add
new patterns for these.

There's room for cleanup and improvement. d16 cases aren't handled.

Fixes #111645

  Log Message:
  -----------
  Remove i16 result mubuf types.

This would only be used if we started using direct i16
values on gfx6/gfx7, but they should legalize all to i32
