One exception here is LoopInfo which must forward-declare it (because the typedef is in LoopPassManager.h which depends on LoopInfo). Also, some includes for LoopPassManager.h were needed since that file provides the typedef. Besides a general consistently benefit, the extra layer of indirection allows the mechanical part of https://reviews.llvm.org/D23256 that requires touching every transformation and analysis to be factored out cleanly. Thanks to David for the suggestion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@278079 91177308-0d34-0410-b5e6-96231b3b80d8
