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.

- 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
llvm-svn: 165477
* 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.

now Reader and Writer subclasses for each file format. Each Reader and
Writer subclass defines an "options" class which controls how that Reader
or Writer operates.
llvm-svn: 157774
Add SharedLibraryFile and ArchiveLibraryFile subclasses of File.
Add command line options to lld-core to set various ResolverOptions settings
and added lots of test cases to verify the options work.

class. Change Resolver to no longer use Platform. Core linking
now issues errors directly. We need to factor that out later.
Rework how Darwin executable writer finds "main" atom. It now
adds to core linking an Atom which has a Reference to "main".

a hello world executable from atoms. There is still much to be flushed out.
Added one test case, test/darwin/hello-world.objtxt, which exercises the
darwin platform.
Added -platform option to lld-core tool to dynamically select platform.

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.

shared library) and AbsoluteAtoms (proxy atoms for absolute address (e.g. ROM)).
Redesign weak importing as can-be-null-at-runtime and can-be-null-at-build-time.
Add lots of test cases for all the above.
