radv: enable lower_sub to fix loop unrolling.
Loop unroll asserts if it hits a sub, we don't really want to lower subs as llvm handles these things, but do this for now, until we can fix loop unroll to work with subs. Fixes: 14ae0bfa5 (radv: Add NIR loop unrolling) Reviewed-by: Bas Nieuwenhuizen <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
