This PR adds well-structured study notes on compiler optimizations for bit counting operations. The documentation clearly demonstrates the performance difference between loop-based implementations and hardware-optimized popcnt instructions. The examples are educational and appropriately show assembly output for both gcc and clang compilers. No blocking issues found.
