This also affects D-YAML: https://github.com/dlang-community/D-YAML/issues/66

https://github.com/dlang/dmd/pull/6913 reverted 6816 which had caused the regression, so this bug is fixed.

Why was this reopened?

(accidentally reopened - sorry)

Changed this to INVALID. A constructor marked nothrow cannot have a field with a throwing destructor, because the destructor can get called if the constructor fails to complete.
