4905 if we have multiple address GIVs that were combined with the same
4906 dst_reg GIV. Note when a new register is created due to unrolling.
4907 * rtl.c (reg_note_name): Add REG_NOALIAS.
4908 * rtl.h (enum reg_note): Similarly.

4923 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
4925 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
4926 in reload_reg_use_in_op_addr do not reach the end.
4927 do not reach the end.
4928 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
4929 RELOAD_FOR_OPERAND_ADDRESS.
