I'd prefer to propose another patch that should be commited with this
one, which fix bugs (say _M_flags & regex_constants::icase, not "&&"),
and do more  "matcher optimization".

It is now more DRY (_RegexTranslator<>) and efficient, but <regex>
takes longer to compile, mainly because now we have 4 times more
_Compiler<> versions :)

Booted and tested with -m32 and -m64 respectively.

Thank you!
