Could not find module ‘GHC.IntWord64’ on GHC 9.2 + i386

[Bodigrim]

As reported by @mpickering at https://gitlab.haskell.org/ghc/ghc/-/issues/20781#note_407377:

On the 9.2 branch the bump seems to fail to build on the i386 job.

It appears that the CPP around the GHC.IntWord64 does attempt to account for its removal:

#if WORD_SIZE_IN_BITS < 64 && __GLASGOW_HASKELL__ < 903
import GHC.IntWord64
#endif

However, the version bound is wrong: the removal was performed in 41d6cfc4, which is present in %9.2.1.
