        * lambda.c (generic_lambda_fn_p): Split out from...
        (maybe_add_lambda_conv_op): ...here.
        * semantics.c (process_outer_var_ref): Don't defer maybe-constant
        variables in a generic lambda.
        * pt.c (instantiate_non_dependent_or_null): New.
        * init.c (constant_value_1): Use it.
        * cp-tree.h: Declare it and generic_lambda_fn_p.
