nice to see this file simplified

I'm thinking this should be "_require", since the raw JS object is not usable
unless a typed wrapper for it exists.

This code does a wonderful job of working around it while staying clean, but I
think it makes a great case that we should have the compiler deal with
marshaling. Would you mind adding a TODO (it can be TODO(jmesserly)) that Frog
should marshal Maps to JS itself? (perhaps based on your NativeMapPrimitiveValue
wrapper)

Do the various versions all have basically the same Dart interface?

I wonder if the code would be simpler to have:
    class TypedArrayBuffer native "*TypedArrayBuffer" {
       ... most of the members here, except ones that need to create instances
...
    }
    class Int8Array extends TypedArrayBuffer ... {
       ... same as before but without repeating the methods in TypedArrayBuffer
...
    }

I'm not 100% sure if that would work, although we play similar tricks in the
DOM, so it might. It would mainly just be a way to factor out the repeated code.

this should be "byteOffset == null" which will check for null and undefined.
(Frog can use either one to represent this missing arg). Same comment on the
line below.
