Timur Kristóf 2c40215ab9 aco/optimizer: Change v_cmp with subgroup invocation to constant. ... When a shader has a comparison with the subgroup invocation id, we can use a constant instead, saving a VALU instruction. When the constant can't be represented as a 64-bit literal, use the s_bfm_b64 instruction to generate it instead, which is still a win.
