1168 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
1169 invisible reference in registers, but then spilled to the stack.
1170 Remove code to emit a second stab for such parameters; it attempts
1171 to describe the value's location by introducing a synthetic C++
1172 `reference' type, and then saying the stack slot has that
1173 reference type. This loses type information (breaking GDB's
1174 `ptype' command, among other things) just to describe a location
