Billy Biggs 9ae7d8a13b Port MMX code from xserver to pixman.
Add an fbpict.c ported from the latest in xserver/fb, including hooks to the MMX code where appropriate. This replaces the old ic.c file.
Replaced by fbpict.c.
Move some X server macros from fbpict.c up into icint.h to keep the diff small.
Add fbmmx and fbpict.c, remove ic.c.
Add a check for the MMX intrinsics. gcc >= 3.4 is required.
