Michael J. Spencer 9ff4be240a Add the core architecture for the lld driver.

building, and running the link. This currently only supports a very basic

lld -flavor ld obj.o -o obj

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

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.

      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.

   writer's fixup handler, applyFixup.
 * Adds method, ELFWriter::buildAtomToAddressMap to that creates a
   mapping from an atom to its runtime address.
