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.
