* 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

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.

First chunk of native object file reader/writer. The lld-core tool now reads YAML file, links, writes that out as native object format, then reads that native file, then writes the YAML to stdout. Thus the test suite tests both YAML reading/writing as well as native object file reading/writing.

A couple of big refactorings: 1) Move most attributes of Atom down to DefinedAtom, so only atoms representing definitions need to implement them. 2) Remove definitionTentative, definitionWeak, mergeDuplicates, and autoHide. Replace with merge and interposable attributes. 3) Make all methods on Atom be virtual so that future object file readers can lazily generated attributes
