2049 if we have multiple address GIVs that were combined with the same
2050 dst_reg GIV. Note when a new register is created due to unrolling.
2051 * rtl.c (reg_note_name): Add REG_NOALIAS.
2052 * rtl.h (enum reg_note): Similarly.

2067 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
2069 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
2070 in reload_reg_use_in_op_addr do not reach the end.
2071 do not reach the end.
2072 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
2073 RELOAD_FOR_OPERAND_ADDRESS.
