0aa39ff054af16be236ee34f4ead2cdc258a48fc ext-inter: Vectorize new masked SAD/SSE functions
We would expect that these new functions would be slower than
the old masked SAD/SSE functions, as they do additional work
(blending two inputs and comparing to a third, rather than
just comparing two inputs).
This is true for the SAD functions, which are about 50% slower
(depending on block size and bit depth). However, the sub-pixel
SSE functions are comparable to the old speed for the accelerated
special cases (xoffset or yoffset = 0 or 4), and are
between 40-90% faster for the generic case.
