As your CDR raises, take in account that you'll be less tankier, and if you're half decent playing Riven, you will be one of the primary objectives in earlier teamfights due your power. This is why most of the times Tabi/Merc's overwhelms Ionian boots, and given that in late game you don't have the damage output of a carry, thus having to spend more time against a single enemy to bring him/her down, building tankier also becomes more suitable than CDR.

However, if you really want that 15% CDR, your only option there is Youmuu's. It's not my style, and personally I don't like Youmuu on Riven, but it's your only chance to get that cooldown reduction and also get some offensiveness. You don't need ASPD, and at least one Bloodthirster is mandatory on any Riven, so Zeke's is out of the scheme. And about Spirit visage... I don't even like it on tankier characters that scalate with HP like Mundo or Volibear, who in fact have healing skills, so I would not even consider it on Riven who doesn't haves any heal besides her health regen and lifesteal.

Hope this helps.
