llvmpipe: Per quad interpolation.
First interpolate the 4 quads upper left corners, then sub-interpolate
each quad pixel. Do the perspective divide once per quad.
Saves some muls and reciprocates. But doesn't seem to make a
noticeable improvement.
It make the code simpler and more compact, so commiting anyway.
