[swift-evolution] [Draft proposal] Faster/lower-level external String initialization

I mostly like the proposal.
However, it seems to me that a single constructor could do the job of both:

init?(cString: UnsafePointer<CChar>, repairingUTF8: Bool = false)

(and similarly for the generic constructor.)

I agree that the static function could be called `decode(_:as:)`.

As for the implementation, I don’t like that the `UnsafePointer<CChar>` constructors choose to crash on a null pointer, when String.fromCString politely returned nil in that situation.
