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. rdar://31680358 Differential Revision: https://reviews.llvm.org/D32424 llvm-svn: 302253
