There have been two incidents recently where bootstrapping has been
broken by removing support for building with 9.2.*.
The process for bumping the minimum required version starts with bumping
the configure version and then other CI jobs such as the bootstrap jobs
have to be updated. We must not silently bump the minimum required
version.
Now we are running a slimmed down validate pipeline it seems worthwile
to test these bootstrap configurations in the full-ci pipeline.

EquationInfo currently contains a list of the equation's patterns together with a CoreExpr that is to be evaluated after a successful match on this equation.
All the match-functions only operate on the first pattern of an equation - after successfully matching it, match is called recursively on the tail of the pattern list.
We can express this more clearly and make the code a little more elegant by updating the datatype of EquationInfo as follows:
data EquationInfo
= EqnMatch { eqn_pat = Pat GhcTc, eqn_rest = EquationInfo }
| EqnDone { eqn_rhs = MatchResult CoreExpr }
An EquationInfo now explicitly exposes its first pattern which most functions operate on, and exposes the equation that remains after processing the first pattern. An EqnDone signifies an empty equation where the CoreExpr can now be evaluated.

This MR addresses #22404. There is a big Note
Note [Occurrence analysis for join points]
that explains it all. Significant changes
* New field occ_join_points in OccEnv
* The NonRec case of occAnalBind splits into two cases:
one for existing join points (which does the special magic for
Note [Occurrence analysis for join points], and one for other
bindings.
* mkOneOcc adds in info from occ_join_points.
* All "bring into scope" activity is centralised in the
new function `addInScope`.
* I made a local data type LocalOcc for use inside the occurrence analyser
It is like OccInfo, but lacks IAmDead and IAmALoopBreaker, which in turn
makes computationns over it simpler and more efficient.
* I found quite a bit of allocation in GHC.Core.Rules.getRules
so I optimised it a bit.
More minor changes
* I found I was using (Maybe Arity) a lot, so I defined a new data
type JoinPointHood and used it everwhere. This touches a lot of
non-occ-anal files, but it makes everything more perspicuous.
* Renamed data constructor WithUsageDetails to WUD, and
WithTailUsageDetails to WTUD
This also fixes #21128, on the way.

In fact these figures seem to vary between platforms; generally worse
on i386 for some reason. The Windows numbers vary by 1% espec in
benchmarks where the total allocation is low. But the geom mean stays
solidly negative, which is good. The "increase/decrease" list below
covers all platforms.
The big win on T13253-spj comes because it has a big nest of join
points, each occurring twice in the next one. The new occ-anal takes
only one iteration of the simplifier to do the inlining; the old one
took four. Moreover, we get much smaller code with the new one:
New: Result size of Tidy Core
= {terms: 429, types: 84, coercions: 0, joins: 14/14}
Old: Result size of Tidy Core
= {terms: 2,437, types: 304, coercions: 0, joins: 10/10}
--------- Runtime perf -----------
No significant changes in nofib results, except a 1% reduction in
compiler allocation.

This commit implements the ability to deprecate certain instances,
which causes the compiler to emit the desired deprecation message
whenever they are instantiated. For example:
module A where
class C t where
instance {-# DEPRECATED "dont use" #-} C Int where
module B where
import A
f :: C t => t
f = undefined
g :: Int
g = f -- "dont use" emitted here
The implementation is as follows:
- In the parser, we parse deprecations/warnings attached to instances:
instance {-# DEPRECATED "msg" #-} Show X
deriving instance {-# WARNING "msg2" #-} Eq Y
(Note that non-standalone deriving instance declarations do not support
this mechanism.)
- We store the resulting warning message in `ClsInstDecl` (respectively, `DerivDecl`).
In `GHC.Tc.TyCl.Instance.tcClsInstDecl` (respectively, `GHC.Tc.Deriv.Utils.newDerivClsInst`),
we pass on that information to `ClsInst` (and eventually store it in `IfaceClsInst` too).
- Finally, when we solve a constraint using such an instance, in
`GHC.Tc.Instance.Class.matchInstEnv`, we emit the appropriate warning
that was stored in `ClsInst`.
Note that we only emit a warning when the instance is used in a different module
than it is defined, which keeps the behaviour in line with the deprecation of
top-level identifiers.

When the offset doesn't fit into the immediate we now just reuse the

offset into a register instead of a special case for CmmRegOff.

why performance metrics for these improve.

This commits adds more performant Enum Int64 and Enum Word64 instances
for 32-bit platforms, replacing the Integer-based implementation.
These instances are a copy of the Enum Int and Enum Word instances with
minimal changes to manipulate Int64 and Word64 instead.
On i386 this yields a 1.5x performance increase and for the JavaScript
back end it even yields a 5.6x speedup.

Warnings when building Hadrian can end up cluttering the output of HLS,
and we've had bug reports in the past about these warnings when building
Hadrian. It would be nice to turn on -Werror on at least one build of
Hadrian in CI to avoid a patch introducing warnings when building
Hadrian.
Fixes #23638

This reverts commit 522bd584f71ddeda21efdf0917606ce3d81ec6cc. And
takes care of the case that I missed in my previous attempt. Namely
the case of an AbsBinds with no type variables and no dictionary
variable.
Ironically, the comment explaining why non-recursive lets were
desugared to recursive lets were pointing specifically at this case
as the reason. I just failed to understand that it was until Simon PJ
pointed it out to me.
See #23550 for more discussion.
