4645bd26aa [Encoder] Add an SSE4.2 implementation of WelsGetNonZeroCount 
Avoid touching some cache lines by using popcnt instead of table
lookups.

Also gives a speedup of ~1.4x on Haswell as compared with SSE2.

3f31aff4dc [Encoder] Add an SSE4.2 implementation of CavlcParamCal 
Use a combination of table lookups and pshufb to convert coefficients
to zero run/level format. Two 16-entry lookup tables are used for a
total of 192 bytes worth of tables. (The existing SSE2 version uses a
table of size 2048 bytes.)

Speedup is ~1.5x-3x as compared with the SSE2 version on Haswell (the
speedup is greater for input with many trailing zeros).

The use of popcnt makes it require SSE4.2. This can be replaced with
a small LUT and accumulation which would reduce the requirement to
SSSE3.

57fc3e9917 [Processing] Add AVX2 VAA routines 
Process 8 lines at a time rather than 16 lines at a time because
this appears to give more reliable memory subsystem performance on
Haswell.

Speedup is > 2x as compared to SSE2 when not memory-bound on Haswell.
On my Haswell MBP, VAACalcSadSsdBgd is about ~3x faster when uncached,
which appears to be related to processing 8 lines at a time as opposed
to 16 lines at a time. The other routines are also faster as compared
to the SSE2 routines in this case but to a lesser extent.
