This reverts commit 8c42237bb2.
Because ssse3 code is used for the reference, the qcoeff and dqcoeff
reference buffers must be aligned.

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.
