forAddr - Make a slot for an aggregate value.

Parameters
quals- The qualifiers that dictate how the slot should be initialied. Only 'volatile' and the Objective-C lifetime qualifiers matter.
isDestructed- true if something else is responsible for calling destructors on this object
needsGC- true if the slot is potentially located somewhere that ObjC GC calls should be emitted for
