PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 VSX SIMD.
This patch addresses Trac ticket #5570. The optimized functions are in file libswscale/ppc/input_vsx.c. Each optimized function name is a concatenation of the corresponding name in libswscale/input.c with suffix _vsx. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
