The changes in `GHC.Utils.Outputable` are the bulk of the patch
and drive the rest.
The types `HLine` and `HDoc` in Outputable can be used instead of `SDoc`
and support printing directly to a handle with `bPutHDoc`.
See Note [SDoc versus HDoc] and Note [HLine versus HDoc].
The classes `IsLine` and `IsDoc` are used to make the existing code polymorphic
over `HLine`/`HDoc` and `SDoc`. This is done for X86, PPC, AArch64, DWARF
and dependencies (printing module names, labels etc.).
