Add a subclass of IntrinsicInst for llvm.assume [nfc]

Add the subclass, update a few places which check for the intrinsic to use idiomatic dyn_cast, and update the public interface of AssumptionCache to use the new class.  A follow up change will do the same for the newer assumption query/bundle mechanisms.
