[MOVED FROM BAD 07/56] gst/deinterlace2/tvtime/vfir.c: Make it possible to use the vfir method on X86 CPUs without MMXEXT too but use the MM...

Original commit message from CVS:
* gst/deinterlace2/tvtime/vfir.c: (deinterlace_line_mmxext),
(deinterlace_line_c), (deinterlace_scanline_vfir):
Make it possible to use the vfir method on X86 CPUs without MMXEXT too
but use the MMXEXT optimized code whenever possible.
