swscale/ppc/swscale_altivec.c: POWER LE support in yuv2planeX_8() delete macro GET_VF() it was wrong
GCC tool had a bug of PPC intrinsic interpret, which has been fixed in GCC 4.9.1. This bug lead to errors in two of our previous patches. We found this when we update our GCC tools to 4.9.1 and by reading the related info on GCC website. We fix our previous error in two separate commits Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
