Now it says "In function ‘<built-in>’". Jakub, could we do better here?

Now, `_Z3foov._omp_fn.0' is demangled as `foo() [clone ._omp_fn.0]'. GCC could
use that instead of just '<built-in>'.

What we perhaps could do is hack up C++ lang_decl_name etc., so that for the
artificially created .omp_fn* functions the diagnostic machinery would instead
print the name of the
original function, perhaps annotated with #pragma omp region of ...
or something similar.
Not sure if we can use for that just if (DECL_ARTIFICIAL
(current_function_decl)
&& name starts with create_omp_child_function_name prefix)
or if we would need to add some special attribute or bit (and if the latter,
if it is worth doing).

No, this isn't a failure of the demangler.  Nor do ever expect these 
functions to ever be demangled.  That they contain the original function
name at all is merely an aid to us the compiler developer.

I don't see that this is any better or worse, from the user's perspective,
than just "__omp_fn.N", which is what we had before the patch.

Unless you can come up with some convincing user usage scenario, I'm not
going to address this problem at all.

actually there is no demangling in the C++ front-end.  What is usually is
giving is just a friendly version of the string (there is a way to do this but
I don't know how).

Now the demangler might need to be expanded to support this (but that is a
different issue from the C++ front-end issue).
