Intel's Mesa Driver Should Have Compute Working For All Hardware Back To Ivy Bridge

Francisco Jerez of Intel was pushing his SIMD32 changes into Mesa Git over night and benefits the driver's ARB_compute_shader support.

With the latest patches, as noted by this commit, ARB_compute_shader should be working on all Gen8+ (Broadwell and newer) hardware plus all Gen7 platforms where it wasn't previously exposed. Originally the Intel driver's ARB_compute_shader support wasn't on for Valley View (Bay Trail) and early Ivy Bridge graphics processors. That's all fixed up now with these SIMD32 patches.

This "i965/fs" work by Francisco amounted to more than 70 patches for getting the SIMD32 support in order for compute support. This work has landed in time for the upcoming Mesa 11.3/12.0 release, which should happen in June but with the branching of it seeming to be delayed it might not appear now until July via stable channels.
