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.
