nir: Add a bunch of algebraic optimizations on logic/bit operations.
Matt and I noticed a bunch of "val <- ior a a" operations in a shader, so we decided to add an algebraic optimization for that. While there, I decided to add a bunch more of them. v2: Delete bogus fand/for optimizations (caught by Jason). total NIR instructions in shared programs: 2023511 -> 2020814 (-0.13%) NIR instructions in affected programs: 149634 -> 146937 (-1.80%) helped: 1032 total i965 instructions in shared programs: 6035392 -> 6035397 (0.00%) i965 instructions in affected programs: 537 -> 542 (0.93%) HURT: 2 Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]> Reviewed-by: Matt Turner <[email protected]>
