Pavel Yaskevich	66a79301b4	[CSDiagnostics] Diagnose contextual closure result mismatches via fixes ... Let's keep track of type mismatch between type deduced for the body of the closure vs. what is requested contextually, it makes it much easier to diagnose problems like: ```swift func foo(_: () -> Int) {} foo { "hello" } ``` Because we can pin-point problematic area of the source when the rest of the system is consistent.

Mark Lacey	70c0e85581	Diagnose Substring-to-String conversions resulting from subscripting. ... When we have a Substring-to-String conversion as a result of subscripting in a context expecting String, we emit the rather generic and unactionable availability diagnostic. Instead, to aid in migration, emit a highly specialized diagnostic and fixit when we're compiling for -swift-version 4.	2017-05-14 23:28:36 -07:00
