    middle-end/97554 - avoid overflow in alloc size compute

    This avoids overflow in the allocation size computations in
    sbitmap_vector_alloc when the result exceeds 2GB.

    2020-10-26  Richard Biener  <rguenther@suse.de>

            * sbitmap.c (sbitmap_vector_alloc): Use size_t for byte
            quantities to avoid overflow.=
