[Intel-gfx] Low performance for trapezoid-heavy stuff

Using the stuff deployed with fedora rawhide ( + 2.7.0 on
xorg-1.6.1) I experience very low performance for trapezoid heavy

E.g. Firefox renders this svg in about 50ms on XAA, whereas it takes
about ~400ms with UXA:

Also QGears2 (a qt benchmark) only reports 7fps instead of 80 when
running on EXA.

Oprofile reports all time is spent in rasterize_edges, could that be
related with the recent change of the cache-mode?

Thanks, Clemens
