So, here's the updated version of this patch, which incorporates all the 
previous comments by Zdenek and Daniel.

The intent of this patch is to consolidate the GMP-to-double-int conversion 
functions between the middle-end and the Fortran front end.  (The Fortran 
portions of this were posted separately, as "4/4" in this series.)  The new 
"wrap" option in mpz_get_double_int is copied from the Fortran version of 
this code.

         * double-int.c (mpz_set_double_int): Moved from
         tree-ssa-loop-niter.c.
         (mpz_get_double_int): Likewise; also, add option to wrap
         out-of-range integers.
         * double-int.h: New prototypes for above.
         * tree.c (get_static_type_bounds): Moved from
         tree-ssa-loop-niter.c; now returns TYPE_MIN_VALUE and
         TYPE_MAX_VALUE if they exist..
         * tree.h: New prototype for above.
         * tree-ssa-loop-niter.c: Adjust mpz_to_double_int and
         get_type_bounds calls.
         (mpz_set_double_int): Move to double-int.c.
         (get_type_bounds): Move to tree.c, rename to
         get_static_type_bounds.
         (mpz_to_double_int): Move to double-int.c, rename to
         mpz_get_double_int.

---------------------------------------------------------------------

Again, bootstrapped and regression-tested on i686-pc-linux-gnu with "make 
check-gcc".  Ok for trunk?
