Stephen Adams d5e8cf7dbd [dart2js] Specialize is- and as- tests for nullable types ...

- '_as' is now specialized on first use, like '_is'.
- '_is' specialization on `T?` that uses `T._is`
- recognize legacy versions of simple type tests (e.g. is int*)

The T? specialization makes a 2x improvement on some of the ListCopy
benchmarks on 'spec-mode' dart2js because some iterators have a T?
check.
