Replace the duplicate coefficient definition in neon implementations
of inverse transform with those from vpx_dsp/txfm_common.h

Change-Id: I4cd9bd9569ab1793dfdbb6f16d80bcb581599f0d

This commit replaces vp9_idct.h with txfm_common.h in many SIMD
implementation files for precise file dependency.

Change-Id: If73dd726bb16537e7494f28538b0a169810f9756

Separate the common coefficient constant into vpx_dsp/txfm_common.h.
Move the SSE2 macro definitions to vpx_dsp/x86/txfm_common_sse2.h.
This clears the use case of vp9_idct.h in vpx_dsp folder.

Avoid scaling the references if they have already been scaled.
Change only affects 1 pass non-svc mode for now.

The RD and load save/code grabs it as groups of four. In practice there
is no change to physical allocations becaquse this is backed by a 16-byte
memalign.

Add vpx_dsp_rtcd.h to the header file list. The od_bin_fdct8x8()
here depends on forward 8x8 2D-DCT.

This fixes a VS build error. Fix by @johannkoenig.

This commit factors out common macro definitions from the forward
and inverse transform implementations into vpx_dsp. It removes
the duplicate macro definitions from encoder and decoder folders.

The msa macros are locally used and should not be named with VP9
prefix.

This commit factors the 4x4, 8x8, and 16x16 2D-DCT forward
transform operations into vpx_dsp folder.

vp9_itrans*_dspr2.c aren't necessary for high bitdepth builds and
notably vp9_itrans8_dspr2.c fails in various configurations using a
codesourcery toolchain:
vp9_itrans8_dspr2.c:31:5: can't find a register in class 'GR_REGS' while reloading 'asm'

This test places 128 in positions that would not be found
in the VP9 filter tables.  The ssse3 code packs this table
into chars and uses the pmaddubsw instruction, which treats
the value as signed.  The ssse3 code checks for 128 in
position 3, skipping the ssse3 code if found, and calls
vp9_convolve8_c().  vp9_convolve8_c() is also used for scaling.
ChangeFilterWorks breaks the ssse3 scaling code found in other
commits.

Eliminates the byte by byte read from bool decoder,  by reading
in a size_t and then shifting it into place.
