Simulate a remote target address space by allocating a seperate chunk of memory for the target and re-mapping section addresses to that prior to execution. Later we'll want to have a truly remote process, but for now this gets us closer to being able to test the remote target functionality outside LLDB. rdar://12157052 llvm-svn: 163216
