This patch only includes inter frame reconstruction using gm parameters when GLOBAL_MOTION and/or VP9_HIGHBITDEPTH are enabled. GM is not currently used when EXT_INTER or DUAL_FILTER is enabled. This will be added in a followup patch. For now, these experiments will take precedence over GLOBAL_MOTION when they are all enabled. Change-Id: I930ddda529c44d7245dbb56db3c9c5524cf45473

- Made source buffers pointers to const. - Renamed vpx_blend_mask6b to vpx_blend_a64_mask. This is more indicative that the function does alpha blending. The 6, or 6b suffix was misleading, as the max mask value (64) does not fit into 6 bits. - Added VPX_BLEND_* macros to use when needing to blend scalars. - Use VPX_BLEND_A256 in combine_interintra to be more explicit about the operation being done. - Added versions of vpx_blend_a64_* which take 1D horizontal/vertical masks directly and apply them to all rows/columns (vpx_blend_a64_hmask and vpx_blend_a64_vmask). The SSE4.1 optimzied horizontal version now falls back on the 2D version. This can be improved upon if it show up high enough in a profile. - All vpx_blend_a64_* functions now support block sizes down to 1x1 (ie: a single pixel). This is for usage convenience. The SSE4.1 optimized versions fall back on the C implementation if w <= 2 or h <= 2. This can again be improved if it becomes hot code. Change-Id: I13ab3835146ffafe3e1d74d8e9cf64a5abe4144d

We can optimize wedge partition selection by pre-computing the residuals of the 2 underlying predictors, and then blend these to compute the sse of the compound predictor, without actually having to compute and subtract the compound predictor. Similarly we can pre-compute a proxy array which we can use to cheaply check which mask sign would have lower sse. Details are in wedge_utils.c. Mathematically these are equivalence transformations, but due to the finite precision the encoder output will be perturbed, though on average this should make 0% difference. ext-inter gains about ~4.5% speedup.

This is purely a refactoring patch and has no functional effect. Uses of these masks can be arranged such that all input blocks are contiguous in memory (stride == block width). In this case 1D versions of operations can be used. 1D vector operations have superior performance over 2D block equivalents as they are more processor cache friendly and they can do away with a second loop overhead.

Increases number of wedges for smaller block and removes wedge coding mode for blocks larger than 32x32. Also adds various other enhancements for subsequent experimentation, including adding provision for multiple smoothing functions (though one is used currently), adds a speed feature that decides the sign for interinter wedges using a fast mechanism, and refactors wedge representations. lowres: -2.651% BDRATE Most of the gain is due to increase in codebook size for 8x8 - 16x16.

When not using ext-tile, there were still dependencies between tile rows due to various tools (eg intra predictors) relying on the above row or above mode info, which can be in the above tile. This is now broken (the same way as it was when ext-tile is enabled) by fixing the appropriate predicates. Change-Id: I107dd0d8481775a792f14e05cfbbd761f16cdc1e

When constructing the intra predictor for rectangular interintra blocks, the last row/column of the first square is copied back into the source image (which is the current reconstructed image buffer) before predicting the second square. The code used to use the height instead of width for vertical rectangles, and vice versa for horizontal rectangles, leading to overwriting the block on the right/below. This leads to an encode/decode mismatch if the right/below block is in a different tile and is encoded before the current block, which did happen with multi-threaded encoding tests. This is now fixed. Change-Id: I073a2a447a98b842b1394d72cc774a78cb296921

Fix 1: in ext-inter + obmc config, properly identify if the left predictor used for obmc is a compound one in the case that the neighbor uses wedgeinterinter pred and we will dump the ALTREF part. This will fix the seg fault in unit test: VP10/AltRefForcedKeyTestLarge.Frame1IsKey/0 Fix 2: in ext-tile + obmc experiment, handle the case that the above block does not fit in the same row tile with the current one, so as to prevent potential crashes.

Remove the restriction that the neighboring predictor cannot be used in obmc prediction if it is an interintra or wedgeinterinter block. The inter predictor of the interintra block, or the first inter predictor(using LAST or GOLDEN frame) of the wedgeinterinter block will be exploited in obmc prediction.
