Move declaration of Rulebase from Rules to CoreSyn
This allow HscTypes to import CoreSyn rather than Rules, which makes
module loops easier to avoid. At one point in my recent travels this
was important; I'm not sure it's so important now, but it's a good
thing anyway.
In any case CoreRule is defined in CoreSyn, so this move make sense.
