Yay, I think it's the time to remove regex_traits::_RegexMask?

Yes, I wanted to get isblank in first, and see how many targets I
broke, then revisit regex.

I don't think we can remove _RegexMask entirely, as we still need
special handling for the "w" class, so maybe something like the
attached.

Alternatively we could replace _M_extended with bool _M_under and not
need to do any bitwise operations like _M_extended & _S_valid_mask.
