    c++: Drop alignas restriction for stack variables.

    Since expand_stack_vars and such know how to deal with variables aligned
    beyond MAX_SUPPORTED_STACK_ALIGNMENT, we shouldn't reject alignas of large
    alignments.  And if we don't do that, there's no point in having
    check_cxx_fundamental_alignment_constraints at all, since
    check_user_alignment already enforces MAX_OFILE_ALIGNMENT.

        PR c++/89357
        * c-attribs.c (check_cxx_fundamental_alignment_constraints): Remove.
