    c++: Readd [LR]ROTATE_EXPR support to constexpr.c [PR94067]

    Since r10-6527-gaaa26bf496a646778ac861aed124d960b5bf549f fold_for_warn
    will perform maybe_constant_value even on some cp_fold produced trees and
    so can include rotate exprs which were removed last fall from constexpr.c

            * constexpr.c (cxx_eval_constant_expression): Do not handle
            RROTATE_EXPR and LROTATE_EXPR.

            * g++.dg/warn/Wconversion-pr94067.C: New test.
