[Mesa-dev] [PATCH] i965: Drop Gen7+ nonsense from brw_ff_gs.c.

[Kenneth Graunke]

brw_ff_gs.c is about using the geometry shader to implement things
that the fixed function ought to do, but doesn't on old hardware.

Gen7+ does not need this.  We should drop the misleading comment
about Gen7 not using geometry shaders.
