necessary until we add analyses to the driver, but I have such an analysis ready and wanted to split this out. This is actually exercised by the existing tests of the new pass manager as the analysis managers are cross-checked and validated by the function and module managers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200901 91177308-0d34-0410-b5e6-96231b3b80d8
