  1. Lots of mostly Float/Double-related tweaks 

      - Haskell unaligned write functions now live in a new module:
      Data.ByteString.Utils.UnalignedWrite
  - The word*HexFixed functions now use unaligned writes;
      likewise Data.ByteString.Builder.RealFloat.Internal.copyWord16.
  - An FFI workaround for unaligned Float/Double writes was added.
  - The data tables in Data.ByteString.Builder.Prim.Internal.Base16
      and Data.ByteString.Builder.RealFloat.{D,F}2S now live in
      the new file cbits/aligned-static-hs-data.c so that we can
      fearlessly perform aligned reads from them.
  - The static Word64 data tables are now stored in
      host-byte-order instead of always little-endian.
  - Data.ByteString.Builder.RealFloat.Internal.digit_table
      is now a static data blob instead of a CAF.
  - All CPP around castFloatToWord32/castDoubleToWord64 now
      lives in Data.ByteString.Builder.Prim.Internal.Floating.
