- string/int keys use identity maps
- construct the correct type rather than relying on factory constructors when possible
- checks if key has identity semantics and use that when possible
- avoid helper calls/casts/etc in implementations
- use native ES6 Map/Set key order tracking
- optimized constructor for map literals
- fixes#30466, const maps are now canonicalized correctly

lib -> the lib folder
private -> the dart:_* libs

I imagine we'll try and focus changes on the last two
