[ARC] Remove Rs5 constraint.

New LRA algorithms require the all the register constraints to be
defined using define_register_constraint keyword. However, Rs5
constraint was not LRA proof. Remove it and replace it by equivalent
Rcd constraint.

xxxx-xx-xx  Claudiu Zissulescu  <claziss@synopsys.com>

* config/arc/arc.md (sibcall_insn): Use Rcd constraint.
(sibcall_value_insn): Likewise.
* config/arc/constraints.md (Rs5): Remove.
