Summary: New pass manager driver passes DebugPM (-debug-pass-manager) flag into individual PassManager constructors in order to enable debug logging. FunctionToLoopPassAdaptor has its own internal LoopCanonicalizationPM which never gets its debug logging enabled and that means canonicalization passes like LoopSimplify are never present in -debug-pass-manager output. Extending FunctionToLoopPassAdaptor's constructor and createFunctionToLoopPassAdaptor wrapper with an optional boolean DebugLogging argument. Passing debug-logging flags there as appropriate.
