    Fortran: Fix typos
    
    gcc/fortran/ChangeLog:
    
            * array.cc (gfc_ref_dimen_size): Fix comment typo.
            * dump-parse-tree.cc (gfc_dump_c_prototypes): Likewise.
            * frontend-passes.cc (cfe_code): Likewise.
            * gfortran.texi: Likewise.
            * resolve.cc (generate_component_assignments): Likewise.
            * simplify.cc (gfc_simplify_this_image): Likewise.
            * trans-expr.cc (trans_scalar_class_assign,
            gfc_maybe_dereference_var): Likewise.
            * intrinsic.texi: Remove word duplication.
            * invoke.texi: Likewise.
