Taewook Oh 62e029142d [IRPrinting] Improve module pass printer to work better with -filter-print-funcs
Summary: Previously module pass printer pass prints the banner even when the module doesn't include any function provided with `-filter-print-funcs` option. This introduced a lot of noise, especailly with ThinLTO. This diff addresses the issue and makes the banner printed only when the module includes functions in `-filter-print-funcs` list.
