PERF: dedupe scanned route fragments
Per: https://bugs.ruby-lang.org/issues/13077 String @- will dedupe strings.
This takes advantage of this by deduping route fragments that are full of duplication usually.

Total retained: 36470010 bytes (322194 objects)
After
Total allocated: 207556847 bytes (2214711 objects)
Total retained: 36327973 bytes (318627 objects) <- object that GC can not collect
So we save 3500 or so RVALUES this way, not the largest saving in the world, but worth it especially for large route files.
