[PATCH v3 1/2] gdi32: Move the loop through each clipped rectangle to the primitive blend funcs.

This is a no-op patch, it's needed for next patch.

I've sent in v4 of this series in which I've tweaked this a bit to give the compiler more of a chance to optimize things as well as using a lookup for the pixel masks.
With a 300x300 32-bpp -> 8-bpp BitBlt I'm getting performance slighty better than Windows if there aren't many distinct RGB values and a little worse if the entire map needs filling.
