    Make vp9_scale_and_extend_frame_ssse3 work for hbd when bitdepth = 8. · 0998a146

    Only works for bitdepth = 8 when compiled with high bitdepth flag.
    4x speed ups for handling 1:2 down/upsampling.
    
    Validated manually for:
    1) Dynamic resize for a single layer encoding
    2) SVC encoding with 3 spatial layers
    Results are bitexact with the patch and the speed gain (~4x) in the
    scaling was verified.
