Lookahead was not consuming typed throw's error argument during lookahead for closures. `atFunctionTypeArrow` did mostly handle it, but only consumed a single token and thus wouldn't match `throws(any Error)`. Handle this in `consumeEffectsSpecifiers` and then use this for both. Fixes apple#2648. Resolves rdar://127750606.
