Ian Romanick 464955bbdd nir/algebraic: Optimize some open-coded extract_i8 ... These were initially observed in Hogwarts Legacy while working on something else entirely. Two compute shaders in that app are helped for spills and fills. On Skylake, one of the shaders benefits from this change, and the other is hurt pretty significantly. About 40 vertex shaders in Shadow of the Tomb Raider were helped for instructions. v2: Use ~0xff instead of 0xffffff00 to ensure the patterns will work properly with all bit sizes. Noticed by Georg. v3: No, really, fix the various errors to ensure the patterns will work properly with all bit sizes. Noticed by Georg. No shader-db changes on any Intel platform. fossil-db: Lunar Lake, Meteor Lake, and DG2 had similar results.
