[PATCH] Remove some unused fields in language_function and named_labels

[Andrew Pinski]

I noticed that we have some unused fields in language_function in 
gfortran
which looks like they were just copied from the C front-end, even though
some of them have seen been removed from the C front-end already.
This patch removes those unused fields and also the unused variable
named_labels which is only set to null.

OK? Bootstrapped and tested on powerpc-darwin with no regressions.

Thanks,
Andrew Pinski

	* fortran/f95-lang.c (language_function): Remove
