It is odd though that LLVM doesn't complain when varargs is used with
CallingConv::X86_StdCall.  With ARM when I upgraded to 0.15.2, it
specifically told me:

[  5%] Generating src/core/demangle_arm64.o
Calling convention does not support varargs or perfect forwarding!
i32 (i8*, i64, i8*, ...)* @snprintf
LLVM ERROR: Broken module found, compilation aborted!
make[3]: *** [runtime/src/core/demangle_arm64.o] Error 1

Then I knew to switch from Fast to C!
