Use std::popcount, ::countl_zero, ::countr_zero functions
...
- Introduced with the C++20 <bit> header
- The problem with __builtin_c(l|t)z() is that 0 as input has an
undefined result (*) and the code did not always check. The std::
versions do not have this issue.
- In some cases, we continue to use buildin_c(l|t)z(), (e.g. in
src/Common/BitHelpers.h) because the std:: versions only accept
unsigned inputs (and they also check that) and the casting would be
ugly.

Official docs:
Some headers from C library were deprecated in C++ and are no longer
welcome in C++ codebases. Some have no effect in C++. For more details
refer to the C++ 14 Standard [depr.c.headers] section. This check
replaces C standard library headers with their C++ alternatives and
removes redundant ones.
