Remove minor unnecessary changes from main javac codebase

[mcimadamore]

This PR undoes some unnecessary changes to the javac code:

• LambdaToMethod still mentions the QUOTABLE flag, which is no longer in use
• Symtab has an helper method to load classes from a string name, but that's not really required
• TreeInfo defines a new helper function to detect super in an expression. Further analysis revealed this was unnecessary (as we can piggy back on the method reference kind instead)
