[fortran,patch] Remove gfc_status and gfc_status_char

[FX Coudert]

> Use putc() rather than fputc(), it's ever so slightly faster.

I briefly thought about that and decided not to care because I never  
remember which is potentially faster :)

Now it's a bit late as I've committed the patch, but I don't think it  
matters too much as there's already mixed use of both in the middle- 
end (and we're only doing it when dumping the parse tree). I'll try  
to remember switching it when I do further work on dump-parse-tree.c,  
like dumping to a file instead of to stdout.

Thanks,
FX
