        * sched-rgn.c: Remove bitset typedef.
        Change bitset to sbitmap in prototypes / variable types.
        Remove bbset_size.
        Remove edgeset_bits.
        Remove edgeset_size.

        (extract_bitlst): Rewrite, now that we have sbitmaps, we can use
        EXECUTE_IF_SET_IN_SBITMAP.
        (split_edges): Rewrite, use sbitmap functions instead of bitset
        operations.
        (schedule_region): Allocate/free sbitmaps, rather than bitsets.
