MachOObjectFile owns a MachOObj, but never frees it. Both MachOObjectFile and MachOObj want to own the MemoryBuffer, though, so we have to be careful and give them each one of their own. Thanks to Greg Clayton, Eric Christopher and Michael Spencer for helping figure out what's going wrong here. rdar://12561773 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168923 91177308-0d34-0410-b5e6-96231b3b80d8
