Subject: [PATCH] Make hello_world test work again

This used to work with the rustc_clean attribute, but doesn't anymore
since my rebase; but I don't know enough about the type checking to find
out what's wrong. The dep graph looks like this:

ItemSignature(xxxx) -> CollectItem(xxxx)
CollectItem(xxxx) -> ItemSignature(xxxx)
ItemSignature(xxxx) -> TypeckItemBody(yyyy)
HirBody(xxxx) -> CollectItem(xxxx)

The cycle between CollectItem and ItemSignature looks wrong, and my
guess is the CollectItem -> ItemSignature edge shouldn't be there, but
I'm not sure how to prevent it.
