Re:Improving performance of original dav1d video decoder

Testing has not been fully completed yet, but if PR merge. rav1d will become even more difficult to optimize.
How much real data alignment helps? Wouldn't -O3 with -Ofast do all code optimization for programmer. Contributor dav1d claims 1-3% growth after his optimization, depending on video dataset payload. He nullified 1% optimization in rav1d, if the real growth was 3%, rav1d will not soon be able to equalize benchmark results.
Another question in theory can Rust be faster than C? If all possible optimizations are applied.
