Implement VCNT instruction (#1963)
* Implement VCNT based on AArch64 CNT
Add tests
* Update PTC version
* Address LDj's comments
* Explicit size in encoding
* Tighter tests
* Replace SoftFallback with IR helper
Co-authored-by: LDj3SNuD <35856442+LDj3SNuD@users.noreply.github.com>
* Reduce one BitwiseAnd from IR fallback
Based on popcount64b from https://en.wikipedia.org/wiki/Hamming_weight#Efficient_implementation
* Rename parameter and add assert
