r300g: implement fast color clear
An initial implementation made by Dave Airlie.
For it to be used, a color-only clear must be invoked and exactly one
point-sampled render target must be set. The render target must be
macrotiled (for us to overcome alignment issues) and bpp must be either
16 or 32.
I can't see a difference in performance. :(
