CPU detection of MMXEXT and probably 3DNOW (not on Athlon yet)

Original commit message from CVS:
CPU detection of MMXEXT and probably 3DNOW (not on Athlon yet)
Renamed the mmxe motion compentation files.
disabled SSE optimisation in ac3dec because it apparently faults..
enable MMXEXT motion compensation on non SSE CPUs (AMD)
