A number of compiler issues that have been reported aren't where the compiler isn't behaving according to the spec, but places where the performance could be improved.
It would be useful to have a new keyword to identify these. This could cover speed issues, code bloat, use of more working memory than necessary, and even requests to make the optimiser smarter. It could cover implementation of language builtins and Phobos functionality alike.
I'm not sure if we should allow it to cover speed/memory usage of the compiler as well, or only of what comes out of it.

I'll add it, but frankly I think you're over emphasizing the keywords.
