<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">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.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">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.

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
