3945 (find_splittable_regs): Likewise. Only create one new pseudo
3946 if we have multiple address GIVs that were combined with the same
3947 dst_reg GIV. Note when a new register is created due to unrolling.
3948 * rtl.c (reg_note_name): Add REG_NOALIAS.
3949 * rtl.h (enum reg_note): Similarly.

3964 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
3966 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
3967 in reload_reg_use_in_op_addr do not reach the end.
3968 do not reach the end.
3969 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
3970 RELOAD_FOR_OPERAND_ADDRESS.
