[Swift] Migrate Swift runtime to Swift 5. 

This switches from using the deprecated hashValue to hash(into:).
It also switches from using index to firstIndex (matching the change in
the standard library).

In the test template, we switch to using String directly instead of
String.characters.

This also switches all the Travis macOS tests to use the Xcode 10.2 / Mojave
image and changes the Linux Swift tests to download Swift 5.0.1.
