+Subject: D3D11: Fix bug with static vertex attributes.
+
+In some specific cases after binding a zero size buffer we could end
+up trying to use a buffer storage that was no longer valid. Fix this
+by ensuring we don't flush dirty bits when we have an early exit due
+to a zero size buffer.
+
+Also adds a regression test.
