BridgeMethodHydrator does not take into account synthetics on sub classes

[Machine-Maker]

Synthetic methods can be generated on subclasses, but then point to a method on the superclass. The invoke instruction used is the INVOKESPECIAL which currently the BridgeMethodHydrator treats as invalid, and so the method isn't hydrated properly.

There is also a check to make sure the class names are the same which isn't required.

And this also will probably requiring changing the HypoHydration.SYNTHETIC_SOURCE to be able to hold multiple methods, as there can be more than 1 synthetic bridge pointing to the same method.
