abb6981f68 Major refactoring: Remove Platform concept. In its place there are 
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.

60d835fa59 Add COFF reader. 
There are no tests for this yet because I still need to finish the
YAML -> COFF converter so we don't get binary files checked in.

20e652d627 Add way to represent static archives in yaml test cases. 
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.

bb963dfb7e Factor out core linking options from Platform in a new ResolverOptions 
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".

b334be1ed2 First implementation of Darwin Platform. It is rich enough to generate 
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.

library depends on Core. This breaks that cycle.

1a6615dc88 Sources now require C++11 to build. 
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.

6bc04c6904 Add support for SharedLibraryAtoms (proxy atoms for exported symbols from a 
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.

55fd6beb00 First chunk of native object file reader/writer. The lld-core tool now reads YAML file, links, writes that out as native object format, then reads that native file, then writes the YAML to stdout. Thus the test suite tests both YAML reading/writing as well as native object file reading/writing.

f4fb2c5ac8 A couple of big refactorings: 1) Move most attributes of Atom down to DefinedAtom, so only atoms representing definitions need to implement them. 2) Remove definitionTentative, definitionWeak, mergeDuplicates, and autoHide. Replace with merge and interposable attributes. 3) Make all methods on Atom be virtual so that future object file readers can lazily generated attributes
