2113 invisible reference in registers, but then spilled to the stack.
2114 Remove code to emit a second stab for such parameters; it attempts
2115 to describe the value's location by introducing a synthetic C++
2116 `reference' type, and then saying the stack slot has that
2117 reference type. This loses type information (breaking GDB's
2118 `ptype' command, among other things) just to describe a location
