enable idct4x4* and idct8x8* which are compatible for 8-bit decodes in
high-bitdepth mode. the adapter narrows 32-bit input to 16, whether the
expansion can be avoided at all in this case remains a TODO. roughly
matches sse2.

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.

7481edb33f vpx_dsp/get_prob: make clip_prob branchless 
+ inline the function directly as there was only one consumer

this is an attempt to reduce the amount of branches to workaround an amd
bug. this change is mildly faster or neutral across x86-64, arm.

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.
