Unfortunately this is outside the scope of the freeze, but I think we
could add it right after the release.

No, it definitely can't. This could easily return the wrong value
(e.g. if c first occurs past offset INT_MAX) and it also invokes UB
(since there's no guarantee memchr does not read past the first
instance of c).
