Populate stack frames with unloaded module info.

This CL hits lots of source files because:
 1. An update to the CodeModule virtual class. I added an is_loaded
  method to specify whether the module is loaded. There were several
  mocks/test classes that needed to be updated with an implementation.
  An alternative to this route would be to modify
  MinidumpUnloadedModule::code_file to prepend "Unloaded_" to the
  module name.

 2. Added an unloaded_modules parameter to
  StackFrameSymbolizer::FillSourceLineInfo.
