// Check that we annotate all compiler-synthesized runtime calls and
// functions with the actual ABI-determined CC. This usually doesn't
// matter as long as we're internally consistent (and the LLVM-default
// CC is consistent with the real one), but it's possible for user
// translation units to define these runtime functions (or, equivalently,
// for us to get LTO'ed with such a translation unit), and then the
// mismatch will kill us.
