rtl-ssa: Don't cost no-op moves
No-op moves are given the code NOOP_MOVE_INSN_CODE if we plan
to delete them later. Such insns shouldn't be costed, partly
because they're going to disappear, and partly because targets
won't recognise the insn code.
gcc/
* rtl-ssa/changes.cc (rtl_ssa::changes_are_worthwhile): Don't
cost no-op moves.
* rtl-ssa/insns.cc (insn_info::calculate_cost): Likewise.
