Composable `ghc*failure`.

[phadej]

With more GHC versions we end up with predicates looking like

ghc92and94and9122failure :: Result -> IO ()
#if (__GLASGOW_HASKELL__ >= 902 && __GLASGOW_HASKELL__ <= 904) || GHC_9122
ghc92and94and9122failure = assertFailure'
#else
ghc92and94and9122failure = assertSuccess
#endif

I suggest that we refactor these so we'd rather write tests as

assertSucceessExcept (ghc92 || ghc94 || ghc9122) $ $(lhsFoo ==~ rhsFoo)
