Title: perf(injector): +29%. Use an array for type lookup instead of a map.

The array is much faster, but we are trading memory for speed:
Each injector will create a O(# of registered types) sized array.
This is probably the right decision, but we should watch large
apps.

This speeds up directive creation in AngularDart by 29%
