PR c++/54372 - unused attribute inactive on dependant entities

In the example of this patch, gcc/g++ invoked with
-Wunused-local-typedefs warns on dependant entities even when those
are decorated with the 'unused' attribute.

This is because in cplus_decl_attributes, save_template_attributes
makes so that the 'unused' attribute is applied to its appertaining
entity only at instantiation time.  But then at parsing time
maybe_warn_unused_local_typedefs checks for TREE_USED before warning.

This patch applies the 'unused' attribute at compilation time.

Tested on x86_64-unknown-linux-gnu against trunk.

PR c++/29028 - Missed unused warning on using declaration

In the example of the patch, g++ fails to warn that the variable N::i
(introduced via a using declaration) is unused.

This is because as we want to emit the warning in poplevel, when we
walk the local bindings returned by getdecls, we forget that a
VAR_DECL introduced by a using declaration is represented by a
TREE_LIST which TREE_VALUE is the VAR_DECL, and we wrongly look for a
bare VAR_DECL.

Fixed thus and tested on x86_64-unknown-linux-gnu against trunk.

        PR fortran/54618
        * trans-expr.c (gfc_conv_procedure_call): Fix INTENT(OUT)
        handling for allocatable BT_CLASS.

From-SVN: r191676

Finish conversion of uses of double_int to the new API.

Some old functionality required new interfaces, and these have been added to
double-int.[hc]:

  double_int::from_pair - static constructor function
  wide_mul_with_sign - double-wide multiply instruction
  sub_with_overflow - subtraction with overlow testing
  neg_with_overflow - negation with overlow testing
  divmod_with_overflow - div and mod with overlow testing

This patch corrects the bootstrap problem on HPPA, via the addition of
sub_with_overflow.  (The overflow properties of negation and addition are
different from subtraction.)

The prior two generations of the interface have been removed.

Some of these old interfaces are still used as static implementation in
double-int.c.

The changed compiler appears 0.321% faster with 80% confidence of being faster.

Tested on x86_64, HPPA, and SPARC.  However, there are changes to the avr
config files, and I have not tested those.
