Conformance fixes:
*) Expand the set of modifiers that can be used with extension methods (strictfp and synchronized now allowed)
*) Ban extension methods that are override-equivalent with members of java.lang.Object
*) Lambda compatibility tweak: void-returning expression lambdas should be compatible with void descriptors
