instruction the key points to is deleted Use weak value handles for both the key and the value. The entry is invalid if either value handle is null. This fixes an assertion failure in BasicAAResult::alias that is caused by UnderlyingObjCPtrCache returning a wrong value. I don't have a test case for this patch that fails reliably. rdar://83984790 (cherry picked from commit f2c7c3c)
