Mark Zhou 515d4bd7ad [dartdevc] Emitting equality checks that disregard 'legacy' wrappers for type objects. ...

Currently does not work for function and generic function types.

Type object equality ignores legacy modifiers but preserves other nullability
semantics. This scheme constructs the runtime type object (normalized) at runtime,
caching it if necessary. This avoids the space overhead of emitting canonicalized
normalized types at compile-time but incurs a cost when runtimeType is called
for the first time per recursive subtype.

See: https://github.com/dart-lang/language/blob/master/accepted/future-releases/nnbd/feature-specification.md#runtime-semantics
