Primops in RULES generate warnings
import GHC.Prim
{-# RULES
"int2Word#/word2Int#" forall x. int2Word# (word2Int# x) = x
#-}
produces the following warning:
Rule "int2Word#/word2Int#" may never fire
because `int2Word#' might inline first
Probable fix: add an INLINE[n] or NOINLINE[n] pragma on `int2Word#'
