Add support for objc_unsafeClaimAutoreleasedReturnValue to the ObjC ARC Optimizer. The main implication of this is: 1. Ensuring that we treat it conservatively in terms of optimization. 2. We put the ASM marker on it so that the runtime can recognize objc_unsafeClaimAutoreleasedReturnValue from releaseRV. <rdar://problem/21567064> Patch by Michael Gottesman! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@258970 91177308-0d34-0410-b5e6-96231b3b80d8
