dirty_deps() changed its meaning now that we also have to check state.isbuilt(). Now, just because dirty_deps() returns true doesn't mean that the file should be unstamped (which forces a rebuild); this might have happened because of state.isbuilt, which means someone already *did* do a rebuild. If we get past state.isbuilt() and into looking at the children, however, and one of the children is dirty, then we should definitely unstamp the current target.
