[PATCH] D26951: Object: Make IRObjectFile own multiple modules and enumerate symbols from all modules.

pcc added dependencies: D26179: Bitcode: Introduce BitcodeWriter interface., D26928: Object: Simplify the IRObjectFile symbol iterator implementation., D26778: Add llvm-modextract tool..

This is the beginnings of multi-module support in IRObjectFile. Note that
the interface still only exposes a single module (i.e. the first one) via
getModule() and takeModule(). A later patch will change the API to expose
all modules.
