In a generator function, the parser rewrites a return statement into a "final"
yield. A final yield used to close the generator, which was incorrect because
the return may occur inside a try-finally clause and so the generator may not
yet terminate.

This adds a bit of boilerplate to some AstVisitors (they now have to
declare their own zone_ member and zone() accessor), but makes it clearer
what DEFINE_AST_VISITOR_SUBCLASS_MEMBERS is for: stack limit checking.

We're moving away from using CompilationInfo as a big bag o' stuff.
Passing in just what we need to several AstVisitors to avoid
increasing the problem.

Adding an AstExpressionVisitor to touch each expression node in
an AST.
Adding TypingReseter to clear the slate after a failed asm.js
validation that has set partial typing information.
Adding a ExpressionTypeCollector to walk the expressions
in an AST and emit them as a string for testing.
Adding tests of the above.
