Richard Wei e5175d595e [Regex] Infer 'Match' type of regex literals. ...

Applies swift-experimental-string-processing#68 in regex literal type inference. Regex literals with captures will have type `Regex<Tuple{n}<Substring, {Captures...}>>`. This is a temporary thing that allows us to define generic constraints on captures. We will switch back to native tuples once we have variadic generics.
