Summary: WinEHPrepare is going to require that cleanuppad and catchpad produce values of token type which are consumed by any cleanupret or catchret exiting the pad. This change updates the signatures of those operators to require/enforce that the type produced by the pads is token type and that the rets have an appropriate argument. The catchpad argument of a `CatchReturnInst` must be a `CatchPadInst` (and similarly for `CleanupReturnInst`/`CleanupPadInst`). To accommodate that restriction, this change adds a notion of an operator constraint to both LLParser and BitcodeReader, allowing appropriate sentinels to be constructed for forward references and appropriate error messages to be emitted for illegal inputs. Also add a verifier rule (noted in LangRef) that a catchpad with a catchpad predecessor must have no other predecessors; this ensures that WinEHPrepare will see the expected linear relationship between sibling catches on the same try. Lastly, remove some superfluous/vestigial casts from instruction operand setters operating on BasicBlocks.
