Summary:
When migrating our codebase from Swift 2.2 -> Swift 2.3 we noticed that when you have a custom subscript with a argument label, the argument label was stripped.
Steps to Reproduce:
1. Define a function such as in Swift 2.2:
```
public subscript(safe index: Int) -> Iterator.Element? {
```
2. Migrate it to Swift 2.3
Expected Results:
Nothing else with a line calling this would change.
Actual Results:
The `safe:` is removed, and replaced with the default subscript syntax.
Version:
Xcode 8 beta 1
Notes:
In our case this is a very frightening bug as the resulting code would still compile correctly, but would no longer be "safe"
