…led via a thunk. For this we need to store the linkage of the “original” method implementation in the vtable. Otherwise DeadFunctionElimination thinks that the method implementation is not public but private (which is the linkage of the thunk). The big part of this change is to extend SILVTable to store the linkage (+ serialization, printing, etc.). fixes rdar://problem/29841635
