pass manager passes' `run` methods. This removes a bunch of SFINAE goop from the pass manager and just requires pass authors to accept `AnalysisManager<IRUnitT> &` as a dead argument. This is a small price to pay for the simplicity of the system as a whole, despite the noise that changing it causes at this stage. This will also helpfull allow us to make the signature of the run methods much more flexible for different kinds af passes to support things like intelligently updating the pass's progression over IR units. While this touches many, many, files, the changes are really boring. Mostly made with the help of my trusty perl one liners. Thanks to Sean and Hal for bouncing ideas for this with me in IRC. llvm-svn: 272978
