In our project, we compile and save bitcodes for later use, but we always try to keep our runtime upstream. Hence, we need readers recognize previous version bitcodes as well, at least in LLVM 3.x. However, the incompatibility happened once in LLVM 3.1, and we deeply hope it won't happen again in the future 3.x version. 

I think it is perfectly reasonable to accept and ignore deplibs in old .bc files.  Bill, can you take care of that?
