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.

* 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.
llvm-svn: 166700
* 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

- 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

Removed architecture dependent .sbss section creation.
Updated test case to show the change in section types and removal of a sbss section.

* 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.

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.

ivars in WriterOptionsMachO instead have its methods compute ivar interactions.
Refactor mach-o Reference Kinds and introduce abstract class KindHandler.
Split up StubAtoms.hpp by architecture. Add support for 32-bit x86 stubs.

* MSVC does not support flexible array members (And neither does C++).
The Mach-O writer test still fails with this, but it all compiles and
all other tests pass.

Add command line options to lld-core to set various ResolverOptions settings

Rework how Darwin executable writer finds "main" atom. It now

Add first linker pass (StubsPass) which looks for calls to shared library
symbols and replaces them with calls to a StubAtom. On ELF system, a "stub"
is a PLT entry. Added a simple test case.
Pass a Platform object to YAML reader and writer for converting fixup kinds
between names and values.
Change output of Resolver to be a File object instead of a vector of Atoms.
Thus, passes operate on a File instead of just Atoms.
Rework how to walk through a File's Atoms. Now iterator based instead of
a method that visits each atom.
