[llvm-dev] Adding custom callback function before/after passes

Hello all,

Is there a way to register callback that runs before/after passes?
PassTimingInfo seems to do a similar thing by calling
PassInstrumentationCallbacks::registerBeforePassCallback /
registerAfterPassCallback, but it is hard-wired with
StandardInstrumentations class.
Do we have something similar to RegisterStandardPasses, so custom callbacks
can be added from somewhere outside LLVM?
