[phobos] Need to start wrapping up this release

[Don Clugston]

The regression bug 4506 (the optimizer generates bad code if you use x
* = -1; inside a loop) is one of the worst DMD bugs ever. We should to
get a release out ASAP.
But we're currently blocked by Phobos:
Unit tests are still failing in std.container. And there's no error
message at all for failing unit tests.
These two issues need to become top priority.
Does anyone know of any other blockers?
