        _Jv_linkExceptionClassTable.
        (_Jv_LinkSymbolTable): Call )_Jv_ThrowNoSuchMethodError.  Call
        _Jv_Defer_Resolution on a method whose ncode is NULL.
        (_Jv_linkExceptionClassTable): New function.
        (_Jv_LayoutVTableMethods): If superclass looks like a constant pool
        entry, look it up.

        (PERSONALITY_FUNCTION): Remove all code related to using a
        Utf8Const* for a match type.  Change match type to be a pointer to
        a pointer, rather than a pointer to a Class.
