Affected subclause: [expr.prim.lambda.capture]

Change: Implicit lambda capture may capture additional entities.

Rationale: Rule simplification, necessary to resolve interactions with constexpr if.

Effect on original feature: Lambdas with a capture-default may capture local entities that were not captured in C++ 2017 if those entities are only referenced in contexts that do not result in an odr-use.
