Curious why we can remove the `moveAndDanglePseudoProbes`(don't need the concept of dangling)? My understanding is we treat dangling as unknown, at pass1 we need to pass this information to the profiled binary. An optimized-out probe won't have samples, it will be treated as zero if not marked as dangling.
