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.
