…ave members Since 9ba892c we always transform `CurrentType` in `ASTPrinter` to be an interface type. This causes issues when the variable type is a generic parameter type. Previously we had `CurrentType` set to a `PrimaryArchetypeType`. With the fix in d93ae06, we are mapping the archetype out of context to a `GenericParamType`. A `GenericParamType`, however, can’t have members, so we’re hitting an assertion when creating a `TypeTransformContext`. Since the entire type transformation in `printTransformedTypeWithOptions` is only affecting type members, we should be able to safely skip over the transformation if `CurrentType` can’t have any members. Fixes rdar://76750555 [SR-14497]
