Summary: The motivation here is LLDB, where we need to fixup relocations in mmapped files before their contents can be read correctly. The MemoryBuffer class does exactly what we need, *except* that it maps the file in read-only mode. WritableMemoryBuffer reuses the existing machinery for opening and mmapping a file. The only difference is in the argument to the mapped_file_region constructor -- we create a private copy-on-write mapping, so that we can make changes to the mapped data, but the changes aren't carried over to the underlying file. This patch is based on an initial version by Zachary Turner.
