Add SSE4_1 highbd version of temporal filter
The SSE4_1 version of temporal filter does not distinguish between bd 10
and bd 12.
Speed up:
Function Level:
| !SS_X | SS_X
!SS_Y | 6.44X | 6.37X
SS_Y | 6.56X | 6.63X
Video Level:
2.5% speed up on basketballpass_240p over 150 frames on speed 1,
bitdepth 10, auto-alt-ref=1
BUG=webm:1591
