1311 invisible reference in registers, but then spilled to the stack.
1312 Remove code to emit a second stab for such parameters; it attempts
1313 to describe the value's location by introducing a synthetic C++
1314 `reference' type, and then saying the stack slot has that
1315 reference type. This loses type information (breaking GDB's
1316 `ptype' command, among other things) just to describe a location
