190c2b4591 Using stride (# of elements) instead of pitch (bytes) in fdct4x4.
Just making fdct consistent with iht/idct/fht functions which all use
stride (# of elements) as input argument.

3d98205fce Move fdct32x32 SSE2 implementation in separate file.
This is in preparation for the SSE2 version of the high-precision
32x32 forward DCT which will share a lot of code with the existing
low precision version used for rate-distortion search.

60dc7375af fixed a compiling problem with MSVC win32 build
The aligned array in parameter list caused win32 build to report
c2719 error. This commit fixed the issue by make the parameter
type a pointer instead of an array.

a32a086d23 Enable sse2 implmentation of 8x8 ADST/DCT
This commit makes use of the butterfly structure to enable the sse2
version implementation of 8x8 ADST/DCT hybrid transform coding.

The runtime of hybrid transform module goes down from 1170 cycles
to 245 cycles. Overall speed-up around 1.5%.

863601c589 Normalize more intrinsic filenames
vp9_dequantize_x86 has only sse2 functions.

vp9_dct_sse2_intrinsics has no namespace collision and can drop
_intrinsics.

vp9_idct_mmx.h is unused.
