Log top-level timing metrics for single-pass analyzer.
Log top-level timing metrics for single-pass analyzer. In order to utilize existing logging infrastructure, we are going to log single-pass metrics as if single pass resolver was a standalone Catalyst rule. We log every run of single-pass resolver as effective.
