Add some functions to the unitialized VM handling
Add some functions to the unitialized VM handling

Only the Class#forName(String) call was handled during the compilation
stage, but VMClassLoader#loadClass and VMClassLoader#findLoadedClass
gets called through various other channels. Add these so we cover most
of the use cases without going too far up the call stack.

This was encountered during compilation of code that did:
   MyClass.class.getClassLoader().loadClass(...)
during an attempt to avoid class initialization. Note that the existing
Class#forName handling doesn't appear to ensure the class is initialized
like would normally happen when Class#forName is called in the running
VM. This is a correctness issue, but is left for another change to
correct.
