r600g: fix replace_gpr_with_pv_ps
Instructions with 3 source operands have no write mask, so we may replace their destinations with PV/PS in the next group even if their dst.write is 0. Note: This is a candidate for the 7.11 branch. Signed-off-by: Vadim Girlin <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
