Fixes#9629
Context
We need some timers and performance indicators for BuildCheck.
Added --analyzeStats option so it will report the time the BuildCheck infrastructure and individual analyzers performed to the command line, otherwise this information is just passed to the logger.
Added timer to a few infrastructure points so we can know how they perform.
