Summary

As a prerequisite to pass-times implementation which needs to time both passes
and analyses, adding instrumentation points to the Analysis Manager.
The are two functional differences between Pass and Analysis instrumentation:

  • the latter does not increment pass execution counter
  • it does not provide ability to skip execution of the corresponding analysis

Since this analysis is now run for analyses as well, order of executions somewhat changes (naturally, those analyses that hit cache are not run, including passinstrumenation one). Full debugging output made perfect sense to me, though it really took some time to figure out a proper set of checks that works for all RUNs, and now I honestly do not remember exact sequence.
