Breaks loops between Stix{Macro,Prim,Integer}.lhs.

Also some CLabel dependencies on MachMisc.

\begin{code}
interface NcgLoop where

import AbsCSyn		( CAddrMode )
import Stix		( StixTree )
import MachMisc		( underscorePrefix, fmtAsmLbl )
import StixPrim		( amodeToStix )

amodeToStix :: CAddrMode -> StixTree
underscorePrefix :: Bool
fmtAsmLbl :: [Char] -> [Char]
\end{code}
