PR c++/60855 - ICE with sizeof VLA capture.
For normal captures we usually look through them within unevaluated context,
but that doesn't work here; trying to take the sizeof of the array in the
enclosing scope tries and fails to evaluate a SAVE_EXPR from the enclosing
scope.
* lambda.c (is_lambda_ignored_entity): Don't look past VLA capture.
