   of function to be called is loaded into a register and then one of these
   labels is called via a BL instruction.  This puts the return address 
   into the link register with the bottom bit set, and the code here 
   switches to the correct mode before executing the function.  Unfortunately
   the target code cannot be relied upon to return via a BX instruction, so
   instead we have to store the resturn address on the stack and allow the
   called function to return here instead.  Upon return we recover the real
   return address and use a BX to get back to Thumb mode.

   There are three variations of this code.  The first,
   _interwork_call_via_rN(), will push the return address onto the
   stack and pop it in _arm_return().  It should only be used if all
   arguments are passed in registers.

   The second, _interwork_r7_call_via_rN(), instead stores the return
   address at [r7, #-4].  It is the caller's responsibility to ensure
   that this address is valid and contains no useful data.

   The third, _interwork_r11_call_via_rN(), works in the same way but
   uses r11 instead of r7.  It is useful if the caller does not really
   need a frame pointer.  */
