Thanks, that helps a lot!

But even that does not cover all the auto insertions. The first
instruction in every translation unit is

typedef char* __builtin_va_list;

which states its source location as <built-in>:102:15. This is not
marked implicit. I guess it's from some internal include directive. In
that case I can just check that it doesn't come from the main file. Are
there any other things like that I should keep an eye on?

I'll also give the bugfix a try, but don't expect too much. Until now I
never had a look at that part of Clang...
