  ghci: fix bootstrapping with 9.12.3-rc1 and above
  
  This patch fixes bootstrapping GHC with 9.12.3-rc1 and above. ghci
  defines `Binary` instance for `HalfWord` in `ghc-heap`, which is a
  proper `newtype` in 9.14 and starting from 9.12.3. Given we don't
  build `ghc-heap` in stage0, we need to fix this predicate so that it
  corresponds to the boot ghc versions that contain the right version of
  `ghc-heap`.
