Gfx12.5 and later allow the use of two 16-bit immediate values in integer MAD. Gfx11 and Gfx12 allow a single immediate for integer MAD, but that is not helpful where. v2: brw_reg_alloc::build_lane_offsets is only used on Gfx12.5+, so the check around using integer MAD is unnecessary. No shader-db or fossil-db changes on any pre-Gfx12.5 platforms. shader-db: Lunar Lake, Meteor Lake, and DG2 had similar results. (Lunar Lake shown) total instructions in shared programs: 17119962 -> 17118441 (<.01%) instructions in affected programs: 65398 -> 63877 (-2.33%) helped: 32 / HURT: 0 total cycles in shared programs: 895433316 -> 895425578 (<.01%) cycles in affected programs: 13437376 -> 13429638 (-0.06%) helped: 30 / HURT: 2 fossil-db: Lunar Lake, Meteor Lake, and DG2 had similar results.
