[PATCH] D11861: [IR] Add token types

[David Majnemer via llvm-commits]

In all fairness, token type doesn't preclude the possibility of a different solution for WinEH.
It might be less odious to encode the funclet property in the `BasicBlock`s themselves.  For example, we could state that some BBs are part a funclet.  Then we would only need to consider `cleanuppad` instructions which lead to `cleanupret` instructions in the same funclet (with a verifier rule that all such `cleanupret` instructions have the same successor).
