  [Clang] Modify Parser::ParseLambdaExpressionAfterIntroducer to check whether the lambda-declarator is valid

We had a couple of crashes due to invalid lambda trailing return types that
were diagnosed but not treated as errors during parsing. So now in
Parser::ParseLambdaExpressionAfterIntroducer(...) after ActOnStartOfLambdaDefinition(...)
we also check if the lambda-declarator is invalid and if so we end up in ActOnLambdaError(...).
