Memory Ownership
----------------
If parseFile() is successful, it either passes ownership of the MemoryBuffer
to the File object, or it deletes the MemoryBuffer. The former is done if the
Atoms contain pointers into the MemoryBuffer (e.g. StringRefs for symbols
or ArrayRefs for section content). If parseFile() fails, the MemoryBuffer
must be deleted by the Reader.
Atoms are always owned by their File object. During core linking when Atoms
are coalesced or stripped away, core linking does not delete them.
Core linking just removes those unused Atoms from its internal list.
