After a remark on a FreeBSD mailing list that the clang man page did not have any list of possible values for the `-std=` flag, I have now attempted to exhaustively list those, for each available language. This also includes a number of deprecated aliases, but since some of those are still used, we might as well include them. They are marked with '(deprecated)`. I also documented the default standard for each language, if there was more than one choice. Suggestions on how to make the values and descriptions line up more nicely in RST are welcome.
