Function-granularity coverage skips functions that are both uncovered and have an uncovered parent. This optimization needs to be tweaked once block coverage and incremental collection is in play, as it is possible to have a function with invocation_count == 0 (i.e. uncovered at function granularity) that still has relevant block-granularity coverage.
