Andreas Kling 36bb2824a6 LibJS: Add StackFrame to avoid indirection in VM register access 
This is a simple trick to generate better native code for access to
registers, locals, and constants. Before this change, each access had
to first dereference the member pointer in Interpreter, and then get to
the values. Now we always have a pointer directly to the values on hand.

Here's how it looks:

    class StackFrame {
    public:
        Value get(Operand) const;
        void set(Operand, Value);

    private:
        Value m_values[];
    };

And we just place one of these as a window on top of the execution
context's array of values (registers, locals, and constants).
