mmap() the entire object file contents into memory with MAP_PRIVATE. We do this because object file contents can change on us and currently this helps alleviate this situation. It also make the code for accessing object file data much easier to manage and we don't end up opening the file, reading some data and closing the file over and over. llvm-svn: 148017
