 // Virtual frames
 //
 // The virtual frame is an abstraction of the physical stack frame.  It
 // encapsulates the parameters, frame-allocated locals, and the expression
 // stack.  It supports push/pop operations on the expression stack, as well
 // as random access to the expression stack elements, locals, and
 // parameters.

   // expected to remain spilled.  The constructor spills the code
   // generator's current frame, but no attempt is made to require it
   // to stay spilled.  It is intended as documentation while the code
   // generator is being transformed.
