Reid Kleckner c2cb560045 [IR] Add AttributeSet to hide AttributeSetNode* again, NFC ...

Summary:
For now, it just wraps AttributeSetNode*. Eventually, it will hold
AvailableAttrs as an inline bitset, and adding and removing enum
attributes will be super cheap.

This sinks AttributeSetNode back down to lib/IR/AttributeImpl.h.
