Merge pull request #225 from VectorCamp/feature/cleanup-compiler-warnings
...
According to https://buildbot-ci.vectorcamp.gr/#/changes/93
most builds succceded and with no compiler warnings. The build failures were only on x86 and Arm for SIMDe builds: x86 because of a bug in SIMDe emulation of own x86 intrinsics in non-native mode and Arm due to clang, unsure if this is actually a bug in SIMDe or clang itself. All the remaining compiler warnings that were suppressed was because they were not possible to fix for the scope of this project.
This PR will close #170 , code quality improvements however will continue with the integration of #222 or similar static code analyzer to CI and continuous refactoring.

Make the match component of SVE truffle constant time
...
There are no significant speed up for 128b vectors but we expect some speedup
for wider vectors compared to the previous linear time implementation of the
match.hpp component

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.

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.
