i965/vec4: Calculate register allocation q values manually.
This fixes a regression in the running time of Piglit introduced by commit 78e9043475d4bed8b50f7e413963c960fa0935bb, which increased the number of register allocation classes set up by the VEC4 back-end from 2 to 16. The algorithm used by ra_set_finalize() to calculate them is unnecessarily expensive, do it manually like the FS back-end does. Reported-by: Mark Janes <> Reviewed-by: Matt Turner <>
