i965: Make rasterization of single and multiple quad prims match.

This is trying to follow the spirit of the invariance rules, though
they're not specific on this point.  Fixes quad-invariance piglit test
while retaining the 22s -> 18s win on glean blendFunc.

This was a regression in c67d9d84f501f145f841c0b981caff6f4dfd936f.
