Move Platform.h to Core as Core depends on Platform.h, and the Platform
...
library depends on Core. This breaks that cycle.

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.

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.

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.

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
