This adds the domtree analysis to the new pass manager. The analysis returns the same DominatorTree result entity used by the old pass manager and essentially all of the code is shared. We just have different boilerplate for running and printing the analysis. I've converted one test to run in both modes just to make sure this is exercised while both are live in the tree. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225969 91177308-0d34-0410-b5e6-96231b3b80d8
