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.

Changes/Additions to SuperVector class * added ==,!=,>=,>,<=,< operators * reworked shift operators to be more uniform and orthogonal, like Arm ISA * Added Unroller class to allow handling of multiple cases but avoid code duplication * pshufb method can now emulate Intel or not (avoids one instruction).
