 There are numerous places within GHC where we use `Int` to represent a
 constant literal for the target. For instance, `CmmUtils` has the
 following:
 {{{#!hs
 -- XXX: should really be Integer, since Int doesn't necessarily cover
 -- the full range of target Ints.
 mkIntCLit :: DynFlags -> Int -> CmmLit
 mkIntCLit dflags i = CmmInt (toInteger i) (wordWidth dflags)
 }}}
 This could go very wrong when cross-compiling from a 32-bit machine to a
 64-bit target.
