This commit integrates ghc-toolchain, the brand new way of configuring
toolchains for GHC, with the Hadrian build system, with configure, and
extends and improves the first iteration of ghc-toolchain.
The general overview is
* We introduce a program invoked `ghc-toolchain --triple=...` which, when run,
produces a file with a `Target`. A `GHC.Toolchain.Target.Target`
describes the properties of a target and the toolchain (executables
and configured flags) to produce code for that target
* Hadrian was modified to read Target files, and will both
* Invoke the toolchain configured in the Target file as needed
* Produce a `settings` file for GHC based on the Target file for that stage
* `./configure` will invoke ghc-toolchain to generate target files, but
it will also generate target files based on the flags configure itself
configured (through `.in` files that are substituted)
* By default, the Targets generated by configure are still (for now) the ones used by Hadrian
* But we additionally validate the Target files generated by
ghc-toolchain against the ones generated by configure, to get a head
start on catching configuration bugs before we transition
completely.
* When we make that transition, we will want to drop a lot of the
toolchain configuration logic from configure, but keep it otherwise.
* For each compiler stage we should have 1 target file (up to a stage compiler we can't run in our machine)
* We just have a HOST target file, which we use as the target for stage0
* And a TARGET target file, which we use for stage1 (and later stages, if not cross compiling)
* Note there is no BUILD target file, because we only support cross compilation where BUILD=HOST
* (for more details on cross-compilation see discussion on !9263)

Fixes #23503.
Now the `-ddump-asm` flag is respected in the wasm backend
NCG, so developers can directly view the generated ASM instead of
needing to pass `-S` or `-keep-tmp-files` and manually find & open
the assembly file.
Ideally, we should be able to output the assembly files in smaller
chunks like in other NCG backends. This would also make dumping assembly
stats easier. However, this would require a large refactoring, so for
short-term debugging purposes I think the current approach works fine.

This commit fixes building ghc with 9.2 as the boostrap compiler.
The ghc-toolchain patch assumed all _STAGE0 options were available, and
forgot to account for this missing information in 9.2.
Ghc 9.2 does not have in settings whether ar supports -l, hence can't
report it with --info (unliked 9.4 upwards).
The fix is to default the missing information (we default "ar supports
-l" and other missing options to False)

It adds a warning -Wincomplete-record-selectors for usages of a record
field access function (either a record selector or getField @"rec"),
while trying to silence the warning whenever it can be sure that a constructor
without the record field would not be invoked (which would otherwise cause
the program to fail). For example:
data T = T1 | T2 {x :: Bool}
f a = x a -- this would throw an error
g T1 = True
g a = x a -- this would not throw an error
h :: HasField "x" r Bool => r -> Bool
h = getField @"x"
j :: T -> Bool
j = h -- this would throw an error because of the `HasField`
-- constraint being solved
See the tests DsIncompleteRecSel* and TcIncompleteRecSel for more examples of the warning.
See Note [Detecting incomplete record selectors] in GHC.HsToCore.Expr for implementation details

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.
--------- Compiler perf -----------

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.

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.
