    libstdc++: Do not use assume attribute for Clang [PR112467]

    Clang has an 'assume' attribute, but it's a function attribute not a
    statement attribute. The recently-added use of the statement form causes
    an error with Clang.

    libstdc++-v3/ChangeLog:

            PR libstdc++/112467
            * include/bits/stl_bvector.h (_M_assume_normalized): Do not use
            statement form of assume attribute for Clang.=
