Detailed Description

The following structure represents a copy of two allocnos.  The
   copies represent move insns or potential move insns usually because
   of two operand insn constraints.  To remove register shuffle, we
   also create copies between allocno which is output of an insn and
   allocno becoming dead in the insn.
