i965/gs: Use new NIR intrinsics.
By performing the vertex counting in NIR, we're able to elide a ton of
useless safety checks around every EmitVertex() call:
total instructions in shared programs: 3952 -> 3720 (-5.87%)
instructions in affected programs: 3491 -> 3259 (-6.65%)
helped: 11
HURT: 0
Improves performance in Gl32GSCloth by 0.671742% +/- 0.142202% (n=621)
on Haswell GT3e at 1024x768.
This should also make it easier to implement Broadwell's "Static Vertex
Count" feature someday.
