[dmd-internals] dmd commit, revision 871

[Don Clugston]

It should be an error in the front-end. Technically, it's still legal,
but it's a ridiculous thing to allow.
About 20% of the code for exception chaining is because of this toxic
waste feature.
(In fact, exception chaining can't work as long as it's legal).

I've created bug 5447 for it.
