[PATCH, nds32] Committed: Look into LO_SUM's operand to determine whether it is a valid address.

Hi, all,

In the nds32_legitimate_address_p function, we should look into LO_SUM's
operand so that we can precisely identify if it is a valid address.
This can help to avoid extra move instruction and improve code generation.

        * config/nds32/nds32.c (nds32_legitimate_address_p): For LO_SUM,
        we need to look into its operand to determine whether it is a valid
        address.
