Subject: [PATCH] Data.Memory.Internal.CompatPrim64: fix 32 bit with GHC >= 9.4

Since 9.4, GHC.Prim exports Word64# operations like timesWord64# even on
i686 whereas GHC.IntWord64 no longer exists. Therefore, we can just use
the ready made solution.

Closes #98, as it should be the better solution.
