Alex Lorenz 98f9fcdb1b Unguarded availability diagnoser should use TraverseStmt instead of 
Base::TraverseStmt when visiting the then/else branches of if statements

This ensures that the statement stack is correctly tracked and correct
multi-statement fixit is generated inside of an if (@available)

Alex Lorenz 9c5c2bfe54 Add a fix-it for -Wunguarded-availability 
This patch adds a fix-it for the -Wunguarded-availability warning. This fix-it
is similar to the Swift one: it suggests that you wrap the statement in an
`if (@available)` check. The produced fixits are indented (just like the Swift
ones) to make them look nice in Xcode's fix-it preview.
