This implements the legacy passes in terms of the new ones. It adds basic testing using explicit runs of the passes. Next up will be wiring the basic output mechanism of opt up when the new pass manager is engaged unless bitcode writing is requested. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199049 91177308-0d34-0410-b5e6-96231b3b80d8
