[PassTiming] reporting time-passes separately for multiple pass instances of the same pass Summary: Refactoring done by rL340872 accidentally appeared to be non-NFC, changing the way how multiple instances of the same pass are handled - aggregation of results by PassName forced data for multiple instances to be merged together and reported as one line. Getting back to creating/reporting timers per pass instance. Reporting was a bit enhanced by counting pass instances and adding #<num> suffix to the pass description. Note that it is instances that are being counted, not invocations of them. time-passes test updated to account for multiple passes being run.
