3215 invisible reference in registers, but then spilled to the stack.
3216 Remove code to emit a second stab for such parameters; it attempts
3217 to describe the value's location by introducing a synthetic C++
3218 `reference' type, and then saying the stack slot has that
3219 reference type. This loses type information (breaking GDB's
3220 `ptype' command, among other things) just to describe a location
