Enabling SEPARATE_GLOBAL_MOTION will remove the ability for a block that uses zeromv with global motion to pick warped_causal or obmc_causal as the motion mode. When this is enabled there is: 0.05% drop on lowres for global + warped enabled 0.15% drop on midres for global + warped enabled 0.12% drop on lowres with global + motion var enabled 0.07% drop on midres with global + motion var enabled No performance change for global, warped, or motion var individually.

This fix was motivated by a code generation bug in g++ on arm, but it seems a good idea generally to disable these unit tests if we're not compiling with optimisations, since the code tested is only intended to be used as inlined functions, and while it's possible to compile without optimisations, the tests become somewhat half-hearted since there are workarounds when there's no inlining (such as for instrinsics requiring immediate values), so the tests would partly test code that wont be used anyway.

Replaces the int64 and int32 divisions in least-squares and gamma or delta computation with a mechanism that decomposes the divisor D such that 1/D = y * 2^-k where y is obtained from a lookup table indexed by 8 highest bits of the difference D - 2^floor(log2(D)). The main complexity is now only from computing this decomposition, which is essentially equivalent to finding floor(log2(D)) (position of highest bit in a 64-bit integer). Also includes an out of memory bug fix and some cleanups. Change-Id: I9247fdff5f6b4191175d4b4656357bfff626f02c

This draft version only pass compiling check, it's not working yet. The following goal is to use new coding system when doing bitstream packing but keep old coding system in RD loop. Change-Id: I224a1581d1cc5c67d73e71558fb77d9faf9c2470

This commit implements support for twopass encoding using the xiphrc experimental rate control system. Most of the code and logic comes from the theora project encoder. Currently support is limited to the bitrate targeting mode of the rate control system and while it does visibly improve quality and does bring rate closer to the target than the one pass mode there's still tuning and bug fixing to be done.

Doing tokenize in the last step of RD loop and then doing packing tokens in bitstream packing phase is hard for debugging. Therefore, we create a frame-level buffer to store the txfm coeffs from the reconstruction in RD loop and then in bitstream packing phase, we can code the txfm coeffs directly.

Fixes some rd-debug mismatches coding cat6 tokens with tx size < 32x32. For these tokens the high extrabits are elided during tokenization and detokenization, but the rd cost was computed with the old tables from VP9 where these high extrabits are always coded.

Frame Super-Resolution is an experiment currently under development. This commit just adds an experimental flag for it. The goal of the experiment is to compress a downsampled version of a frame instead of the full resolution one when bandwidth is limited. The decoder will need to upsample and filter the frame it recieves after decoding. It is thought that this will result in a visually superior result in low bandwidth scenarios.

The initial CDF for each frame is stored in the frame context. CDFs for actual coding are stored in the tile structures, and these are what get adapted. The initial CDF is replaced by an average CDF derived from these tile CDFs. This is carried forward to future frames when backward adaptation is on. CDFs are no longer set from the 8 bit probabilities in backwards adaptation. For now, 8 bit probabilities are maintained for use in the encoder and for symbols which do not have a CDF.
