73c6f59830 Move HuffYUV left prediction to dsputil.

952e872198 Drop unused args from vector_fmul_add_add, simpify code, and rename 
The src3 and step arguments to vector_fmul_add_add() are always zero
and one, respectively.  This removes these arguments from the function,
simplifies the code accordingly, and renames the function to better
match the new operation.

95d36bdbc3 dsputil: declare some arrays 16-byte aligned 
These arrays are passed to functions for which we promise 16-byte
alignment, so make sure we fulfil that promise.
