327a02d77e Use 'packssdw' for loading tran_low_t values
This matches bitdepth_conversion_sse2.asm and produces substantially
better assembly. The old way had lots of 'movzwl' and 'shl' and storing
back to memory before loading into an xmm register.

969957f9f2 Fix real-time compression regression in hbd mode
This commit resolves the compression performance regression in
real-time encoding setting when high bit-depth mode is enabled.

The current solution temporarily disables the SIMD implementations
of vpx_satd, hadamard8x8, and hadamard16x16 in high bit-depth mode.

The commit makes the coding results bit-wise identical between
regular coding pipeline and high bit-depth at profile 0.

32f68cc58c deblock: annotate postproc parameters
Clears a clang static analyzer warning where 'cols' is assumed to be
less than 0, preventing the for loop from executing.

The assembly already requires that the size be 8 or 16 (U/V or Y plane)
and cols is a multiple of 8.

13234d3c43 Remove neon assembly for idct 16x16 and 8x8
Tested using test/partial_idct_test.cc:DISABLED_Speed

Both gcc 4.9 and clang 3.8 from the r13 Android NDK offer improvements
using the intrinsics:
<function>    <clang asm> <gcc asm> <clang intrin> <gcc intrin>
idct16x16_256  1720ms      1703ms    1546ms         1554ms
idct16x16_10   1320ms      1247ms     518ms          488ms
idct16x16_1     107ms       108ms      64ms           68ms
idct8x8_64      924ms       931ms     866ms          989ms
idct8x8_12      826ms       824ms     519ms          514ms
idct8x8_1       172ms       166ms     110ms          125ms

idct8x8_64 isn't quite perfect (slight regression with gcc intrinsics)
but as a counter example idct16x16_10 goes from ~1300ms to ~500ms

On a sample clip, clang improved from 48.5 to 49fps and gcc stayed roughly
stable.

This commit reworks the SSSE3 implementation of the forward 8x8
2D-DCT. It uses a cyclic rotation approach to the temporary xmm
registers. It reduces the average cycles from 158 to 154. The SSE2
version uses 169 cycles.

a6be7ba1aa enable idct*_1_add_neon in high-bitdepth builds
these are compatible as they only load one element of the input so the
larger size of tran_low_t makes no difference in little endian builds.
note the asm is incompatible with big-endian, but there are other points of
failure there so currently it's considered unsupported.

This change will make the highbd txfm input range check more comprehensive

12 signal input bits + 7 bits for 2D forward transform amplification + 5 bits for
1D inverse transform amplification + 1 bit for contingency in rounding and quantizing

0aa3e2564f Add compiler warning flag -Wextra and fix related warnings.
Note: some of these warnings are enabled by a combination of -Wunused
(added earlier) and -Wextra.

Cherry-picked from AOM 4790a69faaec8f03d65f64ff070f6ab4307dbb16

Expands use of (void)x; on unused variables. AOM only supports one codec
in codec_factory.h

Does not include changes to HandleDecodeResult. AOM removed
invalid_file_test.cc which does use the video parameter.

Does not enable -Wextra yet. There are more issues to fix.
