In updates (not post at the time of this writing) to !29884, a change caused many spill and fill regressions shader for OpenGL Tomb Raider. While looking at that shader, I noticed some odd patterns. I initially added these patterns to counteract the regressions caused by the other change, but I had no luck. On Ice Lake... this cuts 99 instructions from the shader. shader-db: All Intel platforms had simliar results.
