7328 dst_reg GIV. Note when a new register is created due to unrolling.

7345 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
7347 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
7348 in reload_reg_use_in_op_addr do not reach the end.
7349 do not reach the end.
7350 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
