When we see 'Class(X' or 'Class::Class(X' and we suspect that it names a
constructor, but X is not a known typename, check whether the tokens could
possibly match the syntax of a declarator before concluding that it isn't
a constructor. If it's definitely ill-formed, assume it is a constructor.
Empirical evidence suggests that this pattern is much more often a
constructor with a typoed (or not-yet-declared) type name than any of the
other possibilities, so the extra cost of the check is not expected to be
problematic.
