The dividing line between compiler builtin, language primitive, standard library or compiler runtime doesn't really exist if you don't want it to. They're all variations on the same theme.

I wonder how one would do DFA minimization with that though. Implement regexp functional equivalence testing so I will not have to! :D

That could be implemented as a pass you load yourself if you don't want to to wait / persuade other people to ship it.
__builtin_regex_compile() __builtin_regex_match()
If there were an ISA out there that had some kind of regular expression feature, those could conceivably be supported with builtins, though.
