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. llvm-svn: 152269
