oxygenation of some arithmetic bitwise functions
pure oxygenation of boost/simd/bitwise
making scalar rol and ror fit the doc and adding test also for rror and rrol
according shr and its oxygenation
according twopower and its oxygenation
polishing scalar unit tests in bitwise
polishing simd bench in bitwise
bad test for ctz
part of oxy had disappeared
adding to twopower oxygen
