Added the ability to extract a ModuleSpecList (a new class) from an ObjectFile. This is designed to be used when you have an object file that contains one or more architectures (MacOSX universal (fat) files) and/or one or more objects (BSD archive (.a files)).

There is a new static ObjectFile function you can call:

size_t
ObjectFile::GetModuleSpecifications (const FileSpec &file,
                                     lldb::offset_t file_offset,
                                     ModuleSpecList &specs)

This will fill in "specs" which the details of all the module specs (file + arch + UUID (if there is one) + object name (for BSD archive objects eventually) + file offset to the object in question).

This helps us when a user specifies a file that contains a single architecture, and also helps us when we are given a debug symbol file (like a dSYM file on MacOSX) that contains one or more architectures and we need to be able to match it up to an existing Module that has no debug info.
