Nothing can generate this currently, but a future commit will.
The Bspec and experimentation support the following limitations:
- Gfx11: Either src0 or src2 can be W or UW.
- Gfx12: Either src0 or src2 can be W or UW.
- Gfx12.5: Both src0 and src2 can be W or UW.
- Gfx20: Both src0 and src2 can be W or UW.
v2: Add missing break statement.
v3: Leave the MAD handling in the case with the other 3 source
instructions. Suggested by Caio.
