df940760f9 aco/optimizer: Propagate scc_needed label through p_wqm.
Without this, RA is confused and adds a bunch of unnecessary moves.

8e961b91c3 aco: optimize v_add+v_lshlrev to v_mad_u32_u24 on GFX6-8
This optimizes v_add(c, v_lshlrev(a, b)) to v_mad_u32_u24(b, 1<<a, c)
if 'a' is a constant (less than or equal to 6 to avoid creating
literals) and 'b' known to be a 16-bit or a 24-bit value.

On GFX9+, this is already optimized to v_lshl_add_u32.

clamp modifier present would be incorrect.

e54c111c45 aco: always use p_parallelcopy for pre-RA copies
Most fossil-db changes are because literals are applied earlier
(in label_instruction), so use counts are more accurate and more literals
are applied.

d169f09e37 aco: be more careful combining additions that could wrap into loads/stores
SMEM does the addition with 64-bits, not 32. So if the original code
relied on wrapping around (for example, for subtraction), it would break.

Apparently swizzled MUBUF accesses also have issues with combining
additions that could overflow. Normal MUBUF accesses seem fine.
