[4.0] Name translation: Allow type name translation when cursor points to constructor call. rdar://33163114

• Explanation: This change allows us to translate type names from Swift to Objc and vice versa by referring only to the constructor calls of that type.
• Scope: Cross-language rename refactoring
• Radar: rdar://33163114
• Risk: Very Low
• Testing: Regression test added

What's up with that Linux failure?

@bob-wilson The linux failure is gone after re-run.
