intel/compiler: make sure swizzle is applied to if condition
This fixes a hang in the following piglit test when GCM moves a UBO load outside of the loop. tests/shaders/ssa/fs-if-def-else-break.shader_test The end NIR ends up looking like this: vec2 32 ssa_3 = intrinsic load_ubo (ssa_2, ssa_0) (0, 1073741824, 0, 0, 8) vec1 32 ssa_4 = mov ssa_3.x vec1 32 ssa_5 = inot ssa_3.y /* succs: block_1 */ loop { ... if ssa_5 { } } Fixes: 1edf67fc ("intel/fs: Generate if instructions with inverted conditions") Reviewed-by:Ian Romanick <ian.d.romanick@intel.com> Part-of: <mesa/mesa!12064> (cherry picked from commit a654e39f)
