42064e5b60 * Add relocation reference support for Hexagon and PowerPC.
- Hexagon has many relocation types, this patch covers just
      a subset, more will be added.
    - PowerPC support was added so that we can verify mixed endian
      environments.
  * Add some basic test cases
  * Update ldd-core to accept -endian flag

dd11020739 This patch makes use of recently added relocation reference data. The bulk
of this is derived from the Mach-O writer.  Reviewed by: Nick Kledzik.
 * Adds loop to SectionChunk::write traverse references calling the
   writer's fixup handler, applyFixup.
 * Adds method, ELFWriter::buildAtomToAddressMap to that creates a
   mapping from an atom to its runtime address.
 * Adds method, ELFWriter::addressOfAtom to return the runtime address
   of the atom.

abb6981f68 Major refactoring: Remove Platform concept. In its place there are
now Reader and Writer subclasses for each file format.  Each Reader and
Writer subclass defines an "options" class which controls how that Reader
or Writer operates.
