Arnold Schwaighofer b102c7f6b4 Parser/Sema/SILGen changes for @_dynamicReplacement(for:) ...

Dynamic replacements are currently written in extensions as

extension ExtendedType {
  @_dynamicReplacement(for: replacedFun())
  func replacement() { }
}

The runtime implementation allows an implementation in the future where
dynamic replacements are gather in a scope and can be dynamically
enabled and disabled.

For example:

dynamic_extension_scope CollectionOfReplacements {
  extension ExtentedType {
    func replacedFun() {}
  }

  extension ExtentedType2 {
    func replacedFun() {}
  }
}

CollectionOfReplacements.enable()
CollectionOfReplacements.disable()
