This includes selecting which driver to emulate, option parsing, invocation
building, and running the link. This currently only supports a very basic
subset of ld for x86_64-linux.

lld -flavor ld obj.o -o obj

or symlink lld as (ld , link, ld64, core) to get the desired behavior without
-flavor.

cl is not attempting to complete a templated class when used in this
context. The conversion forces this to happen.

Thanks to Richard Smith for figuring this out.

This patch changes the following:
  * Use conventional naming for KindHandlers.
  * Add X86 relocation routines.
  * Use std::function instead of function pointers in _fixupHandler map.
  * Change _fixupHandler map from std::map to llvm::DenseMap.
  * Add simple testcase for x86 relocations.

  * Moves enum Scope from DefinedAtom.h to Atom.h
  * Adds scope method to AbsoluteAtom class
  * Updates YAML to print scope of AbsoluteAtoms
  * Update Native Reader/Writer to handle this new, "attribute"
  * Adds testcase

  * 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

  * Updates ReaderELF.cpp contentType method to match ELF.h's logic and now handle
    typeData
  * Add -arch to ldd-core testdriver
  * Add testcase to check typeData
  * Update others to stay in sync with this change.

 * 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.
