Sid Manning 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

Sid Manning 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.

Michael J. Spencer aedfa6a36b Fix MSVC compat. MSVC doesn't have bzero. 
Although the code is not valid to begin with. It is trying to do a raw memory
copy of a non standard-layout type. nameoffset is not guaranteed to directly
follow cmdsize.

This should be properly fixed.
