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.

PR c++/90212
* constexpr.c (potential_constant_expression_1): In a lambda
function, consider a captured variable directly.
