- Frontend: Implicitly import `_StringProcessing` when frontend flag `-enable-experimental-string-processing` is set. - Type checker: Set a regex literal expression's type as `_StringProcessing.Regex<(Substring, DynamicCaptures)>`. `(Substring, DynamicCaptures)` is a temporary `Match` type that will help get us to an end-to-end working system. This will be replaced by actual type inference based a regex's pattern in a follow-up patch (soon). - SILGen: Lower a regex literal expression to a call to `_StringProcessing.Regex.init(_regexString:)`. - String processing runtime: Add `Regex`, `DynamicCaptures` (matching actual APIs in apple/swift-experimental-string-processing), and `Regex(_regexString:)`. Upcoming: - Build `_MatchingEngine` and `_StringProcessing` modules with sources from apple/swift-experimental-string-processing. - Replace `DynamicCaptures` with inferred capture types.
