b6c4a5447c [Decoder/x86] IDCT one block at a time with SSE2 
At lower bitrates, it is overall faster to conditionally do one block
at a time with SSE2 on Haswell and likely other common architectures.
At higher bitrates, it is faster to use the wider routine that IDCTs
four blocks at a time. To avoid potential performance regressions
as compared to MMX, stick with single-block IDCTs with SSE2. There
is still a performance advantage as compared to MMX because the
single-block SSE2 routine is faster than the corresponding MMX
routine.

Stick with four blocks at a time with AVX2 for which that appears
to be consistently faster on Haswell.

98042f1600 [Decoder] Use encoder x86 IDCT routines 
Move asm routines to common. Delete obsolete decoder routines.

Use wider routines where applicable.

~1.07x overall faster decode on a quick 720p30 4Mbps test on Haswell.

with 2 spaces, but astyle doesn't seem to touch the indentation in
these multi-line macros.

2356eb1ff6 Move the memory allocation/deallocation routines to the common library 
They are still used slightly differently in the encoder and decoder;
the decoder uses plain functions while the encoder uses one object
keeping track of the number of allocated bytes, and keeping track
of the requested alignment.

869870e670 Rename the decoder WelsMalloc to WelsMallocz 
This function actually zero-initializes the allocated memory, thus
make this clear in the function name.

This makes the function name match the same behaviour in the encoder.
