AFAII, this couldn't be done using `register[Before/After]PassCallback()` (like here `llvm/lib/IR/PassTimingInfo.cpp`) since profiler timer have to be assuredly finished if started, and that should be done directly by inserting `[start/stop]TimeProfiler()` in `run[Before/After/Pass/Invalidated]()`.
