Switch a vector<pair<const T &, const U &>> to a vector<pair<const T *,

assign a reference.

Replace the 'final' keyword with 'LLVM_FINAL' as GCC 4.6 doesn't support

the keyword.
If anyone cares deeply about the final optimizations with GCC, we might
want to add a version test to the LLVM definition, but I'm perfectly
happy with this just only firing under Clang and modern MSVC builds.

Fix the build with libstdc++ v4.6 on Linux by supplying an explicit move

assignment operator. There is an issue where classes with deleted copy
constructors and user defined move constructors end up with an
implicitly deleted copy constructor that is selected instead of the
implicit move constructor. This is a bit of a hack, but it allows me to
build LLD in a bootstrap with libstdc++ which is my primary goal.

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.
