Implementing -print-before-all/-print-after-all/-filter-print-func support through PassInstrumentation callbacks. - PrintIR routines implement printing callbacks. - StandardInstrumentations class provides a central place to manage all the "standard" in-tree pass instrumentations. Currently it registers PrintIR callbacks. Reviewers: chandlerc, paquette, philip.pfaffe Differential Revision: https://reviews.llvm.org/D50923 llvm-svn: 342896
