Thanks for the explanation, now I get it!

LGTM, with one request for change in the tests



================
Comment at: test/CodeGenObjC/availability-check.m:22
+  // CHECK: br i1 true
+  if (__builtin_available(macos 10.11, *))
+    ;
----------------
Please add a line that verifies that `@available()` uses the builtin as well.
