Implement proper ObjC ARC objc_retainBlock "escape" analysis, so that the optimizer doesn't eliminate objc_retainBlock calls which are needed for their side effect of copying blocks onto the heap. This implements rdar://10361249. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148076 91177308-0d34-0410-b5e6-96231b3b80d8
