1779 invisible reference in registers, but then spilled to the stack.
1780 Remove code to emit a second stab for such parameters; it attempts
1781 to describe the value's location by introducing a synthetic C++
1782 `reference' type, and then saying the stack slot has that
1783 reference type. This loses type information (breaking GDB's
1784 `ptype' command, among other things) just to describe a location
