Change the Compilation object's region member type to a reference, allowing comp->region() to return the same region used by heap memory.
Clean up the initializer list of OMR::Compilation so that members initialization are specified in the same order as their declaration inside the class definition. (Which is the order they get initialized anyway, regardless of their order in the initializer list.)
Change permissions of _signature member and replace its external uses with a call to the signature() method. _signature should still be the first member, as this can significantly ease defect investigations.
Remove _aotClassInfo from OMR::Compilation as it never gets used.
