Correctly rename inherited methods

[HosseinYousefi]

When Foo extends Bar, we're renaming the methods of Foo with the same descriptor to use the same name as the ones in Bar.

This is not always correct. Take:

public class Bar<T> {
  public T method() { /* ... */ }
}

public class Foo extends Bar<String> {}

After the type erasure, Bar's method descriptor becomes ()Ljava/lang/Object;. However Foo's method decriptor is ()Ljava/lang/String; even though technically these two methods must be renamed to the same thing.

Java will also generates a bridge method to preserve polymorphism. Not generating this method will fix any naming clashes, but still the generated method of Foo will get a 1 suffix.
