Serialize and honor whether a particular library should be force-loaded.

Browse Source 
When a module built with -autolink-force-load is imported, add a reference
to a special symbol in the corresponding library so that ld is forced to
link it.

This means the library will be linked into the final binary even if no other
symbols are used (which happens for some of our overlays that just add
category methods to Objective-C classes).
