3942 if we have multiple address GIVs that were combined with the same
3943 dst_reg GIV. Note when a new register is created due to unrolling.

3959 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
3961 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
3962 in reload_reg_use_in_op_addr do not reach the end.
3963 do not reach the end.
3964 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
