Add missing primop documentation (#18454)

- Add three pseudoops to primops.txt.pp, so that Haddock renders
  the documentation
- Update comments
- Remove special case for "->" - it's no longer exported from GHC.Prim
- Remove reference to Note [Compiling GHC.Prim] - the ad-hoc fix is no
  longer there after updates to levity polymorphism.
- Document GHC.Prim
- Remove the comment that lazy is levity-polymorphic.
  As far as I can tell, it never was: in 80e399639,
  only the unfolding was given an open type variable.
- Remove haddock hack in GHC.Magic - no longer neccessary after
  adding realWorld# to primops.txt.pp.

base: Better error message on invalid getSystemTimerManager call

Previously we would produce a rather unhelpful pattern match failure
error in the case where the user called `getSystemTimerManager` in a
program which isn't built with `-threaded`. This understandably confused
the user in #15616.

Fixes #15616.

Add additional tests for #18172 (Followup MR 3543)

There was still one active discussion [thread](https://gitlab.haskell.org/ghc/ghc/-/merge_requests/3543#note_284325) when MR !3543 got merged.

This MR adds the requested tests exercising the changes in
`compiler/GHC/HsToCore/Match/Literal.hs:warnAboutEmptyEnumerations` and its sub-functions.

[fixup 3433] move debugBelch into IF_DEBUG(linker)

The commit in dff1cb3d9c111808fec60190747272b973547c52 incorrectly left
the `debugBelch` function without a comment or IF_DEBUG(linker,)
decoration. This rectifies it.

Needs at least a 8.10 backport, as it was backported in 6471cc6aff80d5deebbdb1bf7b677b31ed2af3d5

Don't store HomeUnit in UnitConfig

Allow the creation of a UnitConfig (hence of a UnitState) without having
a HomeUnit. It's required for #14335.
