- 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.
