This flag was already added to aomedia/master, so bringing it back to
webm/nextgenv2, as part of an effort to get the two codebases in sync.

* changes:
Remove custom rans types
Remove add_token_no_extra.
Remove unused aom_rans_build_cdf_from_pdf
Add the tool used to generate the constrained tokenset.

(cherry picked from aom/master commit 11206c60d930be9d29100567aa67f2a65463852a)
Includes renames in a bunch of places not handled by the original
due to differing tree states.

This brings it in line with the Daala CDFs and will make it easier to
share code.

- av1_fht32x32 AVX2 function level time reduction ~89% compared to C.
- av1_fht32x32_avx2() on DCT_DCT improves 42.62% over aom_fdct32x32_avx2()
But function replacement must go with the corresponding inverse txfm.
- No obvious user level time reduction due to 32x32 TX_TYPE selection.
- Zero high 128b YMM to avoid AVX-SSE transition penalties
(fix 16x16 case).
- Added 32x32 AVX2 unit tests to verify bitexact.
- AVX2 optimization summary:
On CPU i7-6700, based on 16x16/32x32 fwd txfm optimization results:
C to AVX2: function level time reduction, ~86-89%.
SSE2 to AVX2: function level time reduction, ~51%.

This commit renames LIBVPX_TEST_DATA_PATH to LIBAOM_TEST_DATA_PATH,
with a work around for working with jenkins environmnet variables.

Instead of having CLPF write to an entire new frame and
copy the result back into the original frame, make the
filter able to work in-place by keeping a buffer of size
frame_width*filter_block_size and delay the write-back
by one filter_block_size row.
This reduces the cycles spent in the filter to ~75%.

- Unit tests are added for AVX2 SIMD.
- Encoder speed improvement:
AV1 baseline and EXT_TX, three 1080p sequences at bitrate:
800 Kbps, 2 Mbps, 6 Mbps, on i7-6700 CPU, average
user level time reduction: 3.86%.

This test checks if there's any basic change to the bitstream or default
encoder by running an encode and checking that the md5 from the decode
doesn't change.
Any change to the default encoder or bitstream should be accompanied by
a change to the md5 in this file.

(cherry picked from aom/master commit d311d02da55433d20aad6dd88e0bbb992919988d)
The codec name is defined in av1_dx_iface.c
This name needs to match kAV1Name in decode_test_driver.cc.
Otherwise the EndtoEndPSNRTest fails when built with --enable-ext-tile,
(because we need the IsAV1 function to return true.)
