swscale : treat float input data as uint 16bpc
...
Currently float are converted to 16b uint in input part
using src depth (32 bits) in hScale16To19 and hScale16to15,
make an invalid shift for the data
So shift the value when using float input
like 16 bpc uint.

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.
