    c++: constexpr and lambda capture [PR90212]

    This is the same issue as PR86429, just in potential_constant_expression_1
    rather than cxx_eval_constant_expression.  As in that case, when we're
    trying to evaluate a constant expression within a lambda, we don't have a
    constant closure object to refer to, but we can try to refer directly to
the
    captured variable.

Fixed for 9.4/10.2/11.  Is this important to fix in GCC 8?

Not important for me. I don't remember where the yesterday came from.
