loop.c (loop_number): Delete function. 

* loop.c (loop_number): Delete function.  Change all references
        to use uid_loop_num array.
        * loop.h (loop_number): Delete declaration.
        * unroll.c (unroll_loop): Change "loop_number" references to
        use uid_loop_num instead.
Still cleaning up haifa.
