This isn't right. The actual code that's needed here should match what's in
classic codegen, which looks like this:
```
// If we don't have a prototype at all, but we're supposed to
// explicitly use the variadic convention for unprototyped calls,
// treat all of the arguments as required but preserve the nominal
// possibility of variadics.
} else if (CGM.getTargetCodeGenInfo().isNoProtoCallVariadic(
args, cast<FunctionNoProtoType>(fnType))) {
required = RequiredArgs(args.size());
}
```
I'm not sure that's needed for the current bug fix.
