a normal interface for it in Passes.h. This gives us essentially a single interface for running pass managers which are provided from the bottom of the LLVM stack through interfaces at the top of the LLVM stack that populate them with all of the different analyses available throughout. It also means there is a single blob of code that needs to include all of the pass headers and needs to deal with the registry of passes and parsing names. No functionality changed intended, should just be cleanup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225237 91177308-0d34-0410-b5e6-96231b3b80d8
