[Diagnostics] Port contextual mismatches involving nil to new framework
...
Detect and diagnose contextual failures originating in an attempt
to convert `nil` to some other non-optional type e.g.
```swift
let _: Int = nil // can't initialize `Int` with `nil`
func foo() -> Int {
return nil // can't return `nil` from `foo`
}
_ = 1 + nil // there is no `+` overload which accepts `Int` and optional
```

At one point it was used to work around problems with re-type checking
literals in CSApply, but all of our tests appear to pass with this removed.
