This little series lives on top of my VK_KHR_shader_float16_int8 branch, since it depends on having a more flexible combine constants pass, which is included with that work.
A branch with that on this series is available here: https://github.com/Igalia/mesa/tree/itoral/VK_KHR_shader_float16_int8_combine_constants Shader-db results on KBL: total instructions in shared programs: 14965607 -> 14855983 (-0.73%) instructions in affected programs: 3988102 -> 3878478 (-2.75%) helped: 14292 HURT: 59 total cycles in shared programs: 344324295 -> 340656008 (-1.07%) cycles in affected programs: 247527740 -> 243859453 (-1.48%) helped: 14056 HURT: 3314 total loops in shared programs: 4283 -> 4283 (0.00%) loops in affected programs: 0 -> 0 helped: 0 HURT: 0 total spills in shared programs: 27812 -> 24350 (-12.45%) spills in affected programs: 24921 -> 21459 (-13.89%) helped: 345 HURT: 19 total fills in shared programs: 24173 -> 22032 (-8.86%) fills in affected programs: 21124 -> 18983 (-10.14%) helped: 355 HURT: 25 LOST: 0 GAINED: 5 Initially the series included propagation to BFE, BFI2 and BFREV, but that actually led to significantly worse shader-db results, so that part has been removed.
