/* Some info tables to be used when compiled code returns a value to
   the interpreter, i.e. the interpreter pushes one of these onto the
   stack before entering a value.  What the code does is to
   impedance-match the compiled return convention (in R1p/R1n/F1/D1 etc) to
   the interpreter's convention (returned value is on top of stack),
   and then cause the scheduler to enter the interpreter.

   On entry, the stack (growing down) looks like this:

      ptr to BCO holding return continuation
      ptr to one of these info tables.
 
   The info table code, both direct and vectored, must:
      * push R1/F1/D1 on the stack, and its tag if necessary
      * push the BCO (so it's now on the stack twice)
      * Yield, ie, go to the scheduler.

   Scheduler examines the t.o.s, discovers it is a BCO, and proceeds
   directly to the bytecode interpreter.  That pops the top element
   (the BCO, containing the return continuation), and interprets it.
   Net result: return continuation gets interpreted, with the
   following stack:

      ptr to this BCO
      ptr to the info table just jumped thru
      return value

   which is just what we want -- the "standard" return layout for the
   interpreter.  Hurrah!

   Don't ask me how unboxed tuple returns are supposed to work.  We
   haven't got a good story about that yet.
