Add tests for dynamic access in platform and dart2js code. This is a step towards making our own code use Dart 2 rather that Dart 1 semantics. For instance, the js-runtime libraries often use `dynamic` to avoid extra type checking in Dart 1 checked mode, which has the consequence that we have _more_ checking in Dart 2 (or just worse inference baselines). The VM is now optimizing for the typed paths and we should therefore avoid unneeded dynamic accesses in dart2js code itself.
