eb7b0bb50c Optimize vectorscan for aarch64 by using shrn instruction 
This optimization is based on the thread
https://twitter.com/Danlark1/status/1539344279268691970 and uses
shift right and narrow by 4 instruction https://developer.arm.com/documentation/ddi0596/2020-12/SIMD-FP-Instructions/SHRN--SHRN2--Shift-Right-Narrow--immediate--

To achieve that, I needed to redesign a little movemask into comparemask
and have an additional step towards mask iteration. Our benchmarks
showed 10-15% improvement on average for long matches.

2360314f9d Optimized and correct version of movemask128 for ARM 
Closes #99

https://gcc.godbolt.org/z/cTjKqzcvn

Previous version was not correct because movemask thought of having bytes 0xFF. We can fully match the semantics + do it faster with USRA instructions.

5563f0c3b6 firstMatch/lastMatch are now arch-dependent, emulating movemask on non-Intel is very costly, the alternative is almost twice as fast on Arm 2021-10-12 11:51:34 +03:00
