AstGraphBuilder overrides Visit(Expression*) to ensure that even if there is a
stack overflow, a value still gets produced. However, if there was no stack
overflow in the overriden function, but calling
AstVisitor<AstGraphBuilder>::Visit(expr) pushes us over the stack limit, then
the stack overflow check in that function will return without visiting the
expression, and the result will never get pushed.

To fix this, we add a new VisitNoStackOverflowCheck function which avoids the
inner stack check, and call that instead.

Since this depends on the size of C++ stack frames, there is no reliable test
I can add, however regress-635429.js exibits this behavior after
