[Mesa-dev] Add support for GLSL IR saturate()

This patch series add the plumbing to support the GLSL IR instruction saturate(). Previously, saturate is implemented as min/max instructions. Most GPUs, however, can probably perform saturate for free. With these changes, we can allow saturate to be optimized as a single instruction. In additio
