During inference, allow sub-expressions of type dynamic to be cast to the inferred type.
This CL also adds special case support for the case where we are trying to infer a type for a closure literal with a fuzzy type - often these closures are already well-typed (or easily inferable) if we eliminate the fuzziness.
This gets rid of two of the static errors on angular hello world, along with most of the InferableClosure warnings (turning them into InferredTypeClosure infos).
Most of the remaining InferableClosure cases are function literals with block function bodies, which I don't handle in general yet.

cleaner since we only worry about it in one place, and the "this" check is easier and more precise now.
incidentally, I saw a CL go by on the V8 bug, looks like it's close to being fixed

This is a first cut at downwards inference. The interaction with InferableLiteral etc isn't well sorted out yet, so while downwards inference on nested expressions works, there will currently be spurious warnings.

* static methods qualified properly
* static method privacy is now enforced
* avoid static method names banned in strict mode
* avoid variable names banned in strict mode
We might want to relax privacy (for both instance and static), but for now it's nice and consistent with instance methods using ES6 Symbol
