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).

The scheme utilises the MATCH and NMATCH instructions to
scan for 16 characters at the same rate as vermicelli
scans for one.
