7fe357b8c0 split 64-mult hashing into two 32-bit multiplies 
Speed-wise equivalent on x86 and ARM (maybe a tad faster, hard to tell).

Note that the two 32-bit multiples are not strictly equivalent
to the 64-bit one, since we're missing one carry propagation.
In practice, no observable difference was seen because of this
slightly different hashing result.

d484555024 AnimEncoder API: Use timestamp instead of duration as input to Add(). 
When converting from video sources, the duration of current frame
is often unavailable until the next frame. So, we internally convert
timestamps to durations.

use psadbw to perform top row summation; left remains in C as repacking
it into a vector to apply the same operation is too costly.
