[region-isolation] Improve the logging so that we also dump a function's demangled name when processing it in RegionAnalysis. Just trying to improve logging to speed up triaging further. This is useful so that I can quickly find specific closures we process by using the closure numbering (e.x.: closure #1 in XXXX).
