991e344d8c [Encoder] SSE2 4x4 DCT optimizations 
Use a combination of instruction types that distributes more
evenly across execution ports on common architectures.

Do the horizontal DCT without transposing back and forth.

Minor tweaks.

~1.54x faster on Haswell. Should be faster on other architectures
as well.

3088d96978 [Encoder] Add an AVX2 4x4 IDCT implementation 
~2.03x faster on Haswell as compared to the SSE2 version.

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.

Reduce duplication.
