The scanning order has the first 12 coefficients of the 8x8 2D-DCT
sitting in the top left 4x4 block. Hence the partial inverse 8x8
2D-DCT allows to handle cases with eob below 12.

The overall runtime of the inverse 8x8 2D-DCT unit is reduced from
166 cycles (using SSE2) to 150 cycles (using SSSE3).

This commit enables ssse3 assembly implementation of the 8x8
inverse 2D-DCT with only first 10 coefficients non-zero. The
average runtime for this unit goes down from 198 cycles to 129
cycles (34.8% faster).

Added macro to conditionally compile some of the
post-processing functions only when CONFIG_POSTPROC
is defined.

This was causing the build for the generic-gnu target
to fail.

Change-Id: Ibfa447feceb7a0528135025f105be48f97e9965c

The rounding of the ARNR filter output prior to
normalization by the filter strength was incorrect
when strength = 0.

In this case 1 << (strength - 1) would not create the
required rounding of 0, rather it would outrange. This
patch fixes this issue.

This commit enables SSSE3 version full inverse 8x8 2D-DCT and
reconstruction. It makes the runtime of vp9_idct8x8_64_add down
from 256 cycles (SSE2) to 246 cycles.

* changes:
  Use INLINE and include vpx_config.h instead of plain 'inline'
  Use vreinterpret instead of casting neon vector types

This fixes compilation with MSVC.

Change-Id: Iaf7d6b0a0134968a6addf315fde6d852f298db8c

MSVC doesn't support casting neon vector types but requires using
vreinterpret.
