In QTBUG-102598 we've seen a situation where either the builtin types were incomplete or the literal binding analysis failed to assign them to the literal bindings. In particular, regularExpression was missing.

We're fixing the bug by not performing the literal binding analysis in qmlcachegen and qmlsc anymore, but that only postpones the problem until someone hits the same situation with qmltc or qmllint.

We need to find out what is actually happening.
