Begin adding static dependence information to passes, which will allow us to

perform initialization without static constructors AND without explicit initialization
by the client. For the moment, passes are required to initialize both their
(potential) dependencies and any passes they preserve. I hope to be able to relax
the latter requirement in the future.

For PR780:

1. Fix the macros in IncludeFile.h to put everything in the llvm namespace
2. Replace the previous explicit mechanism in all the .h and .cpp files

This gets us a consistent mechanism throughout LLVM for ensuring linkage.
Next step is to make sure its used in enough places.
