This reverts commit 8c42237bb200253931c49e2c530838f3a877dd65.
Because ssse3 code is used for the reference, the qcoeff and dqcoeff
reference buffers must be aligned.

This reverts commit f60d1dcd3de46f72bafc5eeef481bd1a4e203301.
Reason for revert: <INSERT REASONING HERE>
Failures in AVX/VP9QuantizeTest in nightly tests.

Still does not pass tests. Does match the previous assembly, although
saving the sign before multiplying is dubious.

Adds an early exit based on ptest. Slightly slower than ssse3 in the
full case because of the extra check, but potentially faster if lots of
rows can be skipped.
Very close in speed to the assembly.
Can run in 32 bit, unlike the assembly. Allows reworking the function
prototype to use structs.

Fairly minor differences from sse2. pabsw and psignw are the big gains.
Also re-uses some values in eob calculation to avoid an extra pcmp.
Fixes test failures in HBD and OS X builds.
Allows using it in 32bit builds, where it is about 40% faster than sse2.
Substantially faster than the assembly for skip_block. 10-20% faster the
rest of the time.

With skip block or coeff < zbin it is about twice as fast as C.
If most coeff values are > zbin it is about 10-15x as fast as C.

The function was originally written with HBD in mind. Enable it and
configure the tests.

Roughly 2x speedup. Since the only change for HBD is to store(), the
improvement appears to hold there as well.

Move the tran_low_t helper functions to a new file. Additional
load/store functions will be added here.

Provides over 15x speedup for width > 8.
Due to smaller loads and shifting for width == 8 it gets about 8x
speedup.
For width == 4 it's only about 4x speedup because there is a lot of
shuffling and shifting to get the data properly situated.
