    c++: Preserve location in maybe_constant_value.

    If cxx_eval_outermost_constant_expr doesn't change the argument, we really
    shouldn't unshare it when we try to fold it again.

        PR c++/92852
        * constexpr.c (maybe_constant_value): Don't unshare if the cached
        value is the same as the argument.
