Michael Gottesman f23af8bfd8 [objc-arc] Convert the one directional retain/release relation assert to a conditional check + fail. ... Due to the previously added overflow checks, we can have a retain/release relation that is one directional. This occurs specifically when we run into an additive overflow causing us to drop state in only one direction. If that occurs, we should bail and not optimize that retain/release instead of asserting. Apologies for the size of the testcase. It is necessary to cause the additive cfg overflow to trigger. rdar://15377890 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194083 91177308-0d34-0410-b5e6-96231b3b80d8		2013-11-05 16:02:40 +00:00
