Merge #13249: Make objects in range declarations immutable by default. Avoid unnecessary copying of objects in range declarations. 

f34c8c466a Make objects in range declarations immutable by default. Avoid unnecessary copying of objects in range declarations. (practicalswift)

Pull request description:

  Make objects in range declarations immutable by default.

  Rationale:
  * Immutable objects are easier to reason about.
  * Prevents accidental or hard-to-notice change of value.

Tree-SHA512: cad69d35f0cf8a938b848e65dd537c621d96fe3369be306b65ef0cd1baf6cc0a9f28bc230e1e383d810c555a6743d08cb6b2b0bd51856d4611f537a12e5abb8b
