You don't need a new func here; you can use func_regexp for both the one
and two argument case.

That first entry in the array should be T_NODESET - which means we also
need a test for passing a nodeset to regexp

Something like this should work (also allow "" as a flag):

static void func_regexp(struct state *state, int nargs) {
    int nocase = 0;
    ensure_arity(1, 2);

    if (nargs == 2) {
      struct value *f = pop_value(state);
      if (STREQ("i", f->string))
          nocase = 1;
      else if (STRNEQ("", f->string))
          STATE_ERROR(state, PATHX_EREGEXPFLAG);
    }

    func_regexp_or_glob(state, 0, nocase);
}
