    expr: Handle BITINT_TYPE in count_type_elements [PR112881]

    The following testcaser ICEs during gimplification, because
    count_type_elements doesn't handle BITINT_TYPE.  It should handle it like
    other integral types.

            PR middle-end/112881
            * expr.cc (count_type_elements): Handle BITINT_TYPE like
INTEGER_TYPE.

            * gcc.dg/bitint-50.c: New test.
