Richard Smith 24ad121582 Add -std=c++20 flag, replace C++2a with C++20 throughout the Clang ... user interface and documentation, and update __cplusplus for C++20. WG21 considers the C++20 standard to be finished (even though it still has some more steps to pass through in the ISO process). The old flag names are accepted for compatibility, as usual, and we still have lots of references to C++2a in comments and identifiers; those can be cleaned up separately.		2020-02-18 16:16:37 -08:00
