cb94b9d7b7 Fix segfaults on allocation failure (#4) 
Throw std::bad_alloc instead of returning nullptr from
ue2::AlignedAllocator. Allocators for STL containers are expected never
to return with an invalid pointer, and instead must throw on failure.
Violating this expectation can lead to invalid pointer dereferences.

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.
