Add 'docWithStyle' to improve codegen
This new combinator
docWithStyle :: IsOutput doc => doc -> (PprStyle -> SDoc) -> doc
let us remove the need for code to be polymorphic in HDoc
when not used in code style.

Fix finaliseArgBoxities for OPAQUE function
We never do worker wrapper for OPAQUE functions, so we must
zap the unboxing info during strictness analysis.
This patch fixes #22502

Revert "rts: Drop racy assertion"
The logic here was inverted. Reverting the commit to avoid confusion
when examining the commit history.
This reverts commit b3eacd64fb36724ed6c5d2d24a81211a161abef1.

rts: Drop racy assertion
0e274c39bf836d5bb846f5fa08649c75f85326ac added an assertion in
`dirty_MUT_VAR` checking that the MUT_VAR being dirtied was clean.
However, this isn't necessarily the case since another thread may have
raced us to dirty the object.

configure: Fix escaping of `$tooldir`
In !9547 I introduced `$tooldir` directories into GHC's default link and
compilation flags to ensure that our C toolchain finds its own headers
and libraries before others on the system. However, the patch was subtly
wrong in the escaping of `$tooldir`. Fix this.
Fixes #22561.

Fix contification with stable unfoldings (#22428)
Many functions now return a `TailUsageDetails` that adorns a `UsageDetails` with
a `JoinArity` that reflects the number of join point binders around the body
for which the `UsageDetails` was computed. `TailUsageDetails` is now returned by
`occAnalLamTail` as well as `occAnalUnfolding` and `occAnalRules`.
I adjusted `Note [Join points and unfoldings/rules]` and
`Note [Adjusting right-hand sides]` to account for the new machinery.
I also wrote a new `Note [Join arity prediction based on joinRhsArity]`
and refer to it when we combine `TailUsageDetails` for a recursive RHS.
I also renamed
* `occAnalLam` to `occAnalLamTail`
* `adjustRhsUsage` to `adjustTailUsage`
* a few other less important functions
and properly documented the that each call of `occAnalLamTail` must pair up with
`adjustTailUsage`.
I removed `Note [Unfoldings and join points]` because it was redundant with
`Note [Occurrences in stable unfoldings]`.
While in town, I refactored `mkLoopBreakerNodes` so that it returns a condensed
`NodeDetails` called `SimpleNodeDetails`.
Fixes #22428.
The refactoring seems to have quite beneficial effect on ghc/alloc performance:

Only gc sparks locally when we can ensure marking is done.
When performing GC without work stealing there was no guarantee that
spark pruning was happening after marking of the sparks. This could
cause us to GC live sparks under certain circumstances.
Fixes #22528.

Make `GHC.Tc.Errors.Reporter` take `NonEmpty ErrorItem` rather than `[ErrorItem]`, which lets us drop some panics.
Also use the `BasicMismatch` constructor rather than `mkBasicMismatchMsg`, which lets us drop the "-Wno-incomplete-record-updates" flag.

ci: improve nix-shell for gen_ci.hs and fix some ghc/hlint warnings
- Add a ghc environment including prebuilt dependencies to the
nix-shell. Get rid of the ad hoc cabal cache and all dependencies
are now downloaded from the nixos binary cache.
- Make gen_ci.hs a cabal package with HLS integration, to make future
hacking of gen_ci.hs easier.
- Fix some ghc/hlint warnings after I got HLS to work.
- For the lint-ci-config job, do a shallow clone to save a few minutes
of unnecessary git checkout time.

Add a missing checkEscapingKind
Ticket #22743 pointed out that there is a missing check,
for type-inferred bindings, that the inferred type doesn't
have an escaping kind.

testsuite: req_smp --> req_target_smp, req_ghc_smp
See #22630 and !9552
This commit:
- splits req_smp into req_target_smp and req_ghc_smp
- changes the testsuite driver to calculate req_ghc_smp
- changes a handful of tests to use req_target_smp instead of req_smp
- changes a handful of tests to use req_host_smp when needed
The problem:
- the problem this solves is the ambiguity surrounding req_smp
- on master req_smp was used to express the constraint that the program
being compiled supports smp _and_ that the host RTS (i.e., the RTS used
to compile the program) supported smp. Normally that is fine, but in
cross compilation this is not always the case as was discovered in #22630.
The solution:
- Differentiate the two constraints:
- use req_target_smp to say the RTS the compiled program is linked
with (and the platform) supports smp
- use req_host_smp to say the RTS the host is linked with supports smp
WIP: fix req_smp (target vs ghc)
add flag to separate bootstrapper
split req_smp -> req_target_smp and req_ghc_smp
update tests smp flags
cleanup and add some docstrings
only set ghc_with_smp to bootstrapper on S1 or CC
Only set ghc_with_smp to bootstrapperWithSMP of when testing stage 1
and cross compiling
test the RTS in config/ghc not hadrian
re-add ghc_with_smp
fix and align req names
fix T11760 to use req_host_smp
test the rts directly, avoid python 3.5 limitation
test the compiler in a try block
align out of tree and in tree withSMP flags
mark failing tests as host req smp
testsuite: req_host_smp --> req_ghc_smp
Fix ghc vs host, fix ghc_with_smp leftover
