Add weak symbol support to RuntimeDyld

Authored by loladiro on Jan 13 2015, 7:47 AM.



Support weak symbols by first looking up if there is an externally visible symbol we can find, and only if that fails using the one in the object file we're loading. I'd like some feedback if these semantics seem correct, since the semantics of weak symbols during dynamic linking are always tricky.
