Nit: I'm not sure that we need this method as is since, it simply goes back and
iterates over the initializers to find the supercall which the loop on line 882
has already done.

+1. this is not new code and we should refactor. I plan to work on cleaning some
of this as part of the constructor init order bug.

+        if (constructorInvocation != null) {
           // Call the super initializer function in the initializer.
           // Compute the super constructor initializer to call.
           ConstructorElement superElement = (ConstructorElement) initInvocation.getSymbol();
