[X86] Extend varargs test
This extends the existing x86-64-varargs test by passing enough arguments that they need to be passed in memory, and by passing them in reverse order, using va_arg for each argument to retrieve them and restoring them to the correct order, and by using va_copy to have two va_lists to use with va_arg.
