f90960983c [Encoder] Add single-block SSE2 4x4 DCT/IDCT routines 
We do four blocks at a time when possible, but need to handle
single blocks at a time for intra prediction.

~2.31x speedup over MMX for the DCT on Haswell.
~1.92x speedup over MMX for the IDCT on Haswell.

7486de2844 [Encoder] AVX2 DCT tweaks 
Do some shuffling in load/store unpack/pack to save some
work in horizontal DCTs.

Use a few 128-bit broadcasts to compact data vectors a bit.

~1.04x speedup for the DCT case on Haswell.
~1.12x speedup for the IDCT case on Haswell.

144ff0fd51 [Encoder] SSE2 4x4 IDCT optimizations 
Use a combination of instruction types that distributes more
evenly across execution ports on common architectures.

Do the horizontal IDCT without transposing back and forth.

Minor tweaks.

~1.14x faster on Haswell. Should be faster on other architectures
as well.

b9adbcf37c [UT] Add missing SSE2 4x4 IDCT test 
IDCT input is defined in such a way that the intermediate values
cannot legally overflow an int16_t. The use of random values
as input causes such overflows. This results in implementation-
dependent output depending on which type is used to hold
intermediate results. Use a template for the test reference
implementation to test implementations with different
intermediate representation.

8764231784 [UT] Improve DCT tests 
Initialize input arrays with different random values.

Otherwise, the input to the DCT routines is effectively
all zero values after taking the difference.
