    Change const basic_block to const_basic_block.
    
            * gimple-range-cache.cc (*::set_bb_range): Change const basic_block to
            const_basic_block..
            (*::get_bb_range): Ditto.
            (*::bb_range_p): Ditto.
            * gimple-range-cache.h: Change prototypes.
