Add -fno-cse to T15426 and T18964
This -fno-cse change is to avoid these performance tests depending on
flukey CSE stuff. Each contains several independent tests, and we don't
want them to interact.
See #23925.
By killing CSE we expect a 400% increase in T15426, and 100% in T18964.
Metric Increase:
T15426
T18964

Tiny refactor
canEtaReduceToArity was only called internally, and always with
two arguments equal to zero. This patch just specialises the
function, and renames it to cantEtaReduceFun.
No change in behaviour.

spec-constr: Lift argument limit for SPEC-marked functions
When the user adds a SPEC argument to a function, they are informing us
that they expect the function to be specialised. However, previously
this instruction could be preempted by the specialised-argument limit
(sc_max_args). Fix this.
This fixes #14003.

Fix eta reduction
Issue #23922 showed that GHC was bogusly eta-reducing a join point.
We should never eta-reduce (\x -> j x) to j, if j is a join point.
It is extremly difficult to trigger this bug. It took me 45 mins of
trying to make a small tests case, here immortalised as T23922a.

Profiling: Properly escape characters when using `-pj`.
There are some ways in which unusual characters like quotes or others
can make it into cost centre names. So properly escape these.

Use correct FunTyFlag in adjustJoinPointType
As the Lint error in #23952 showed, the function adjustJoinPointType
was failing to adjust the FunTyFlag when adjusting the type.
I don't think this caused the seg-fault reported in the ticket,
but it is definitely. This patch fixes it.
It is tricky to come up a small test case; Krzysztof came up with
this one, but it only triggers a failure in GHC 9.6.

base: Advertise linear time of readFloat
As noted in #23538, `readFloat` has runtime that scales nonlinearly in
the size of its input. Consequently, its use on untrusted input can
be exploited as a denial-of-service vector. Point this out and suggest
use of `read` instead.
See #23538.

Pass quantified tyvars in tcDefaultAssocDecl
This commit passes the correct set of quantified type variables written
by the user in associated type default declarations for validity
checking. This ensures that validity checking of associated type defaults
mirrors that of standalone type family instances.

Avoid panic in mkGADTVars

Adjust reporting of unused tyvars in data FamInsts
This commit adjusts the validity checking of data family
instances to improve the reporting of unused type variables.
See Note [Out of scope tvs in data family instances] in GHC.Tc.Validity.
The problem was that, in a situation such as
data family D :: Type
data instance forall (d :: Type). D = MkD
the RHS passed to 'checkFamPatBinders' would be the TyCon app
R:D d
which mentions the type variable 'd' quantified in the user-written
forall. Thus, when computing the set of unused type variables in
the RHS of the data family instance, we would find that 'd' is used,
and report a strange error message that would say that 'd' is not
bound on the LHS.
To fix this, we special-case the data-family instance case,
manually extracting all the type variables that appear in the
arguments of all the data constructores of the data family instance.
Fixes #23778

Unused tyvars in FamInst: only report user tyvars
This commit changes how we perform some validity checking for
coercion axioms to mirror how we handle default declarations for
associated type families. This allows us to keep track of whether
type variables in type and data family instances were user-written
or not, in order to only report the user-written ones in
"unused type variable" error messages.
Consider for example:
{-# LANGUAGE PolyKinds #-}
type family F
type instance forall a. F = ()
In this case, we get two quantified type variables,
(k :: Type) and (a :: k); the second being user-written, but the first
is introduced by the typechecker. We should only report 'a' as being
unused, as the user has no idea what 'k' is.
Fixes #23734

Validity: refactor treatment of data families
This commit refactors the reporting of unused type variables in type

Remove `ghc-cabal`
It is dead code since the Make build system was removed.
I tried to go over every match of `git grep -i ghc-cabal` to find other
stray bits. Some of those might be workarounds that can be further
removed.

hadrian: Make it easier to debug Cabal configure
Right now, output is squashed. This make per-package configure scripts
extremely hard to maintain, because we get vague "library is missing"
errors when the actually probably is usually completely unrelated except
for also involving the C/C++ toolchain.
(I can always pass `-VVV` to Hadrian locally, but these errors are
subtle and I often cannot reproduce them locally!)
`--disable-option-checking` was added back in
75c6e0684dda585c37b4ac254cd7a13537a59a91 but seems to be a bit overkill;
if other flags are passed that are not recognized behind the two from
Cabal mentioned in the former comment, we *do* want to know about it.

hadrian: Increase verbosity of certain cabal commands
This is a hack to get around the cabal function we're calling
*decreasing* the verbosity it passes to another function, which is the
stuff we often actually care about. Sigh.
Keeping this a separate commit so if this makes things too verbose it is
easy to revert.

rts: Move most external symbols logic to the configure script
This is much more terse because we are programmatically handling the
leading underscore.
`findPtr` however is still handled in the Cabal file because we need a
newer Cabal to pass flags to the configure script automatically.

Try not doing floatConsts
This avoid flattening, and generating lots of top level
bindings. Instead do it in late-lambda-lift.
I moved late-lambda-lift to run with -O because it is cheap
and valuable. That's a somewhat orthogonal change, probably
should test separately.

Wibbles to fix VSM
SetLevels floats out top level things if:
bottoming (possibly lambda) and non-strict
expandable and not a con-app
The not-con-app bit is to avoid flattening big data structures
Expandable bit is because specConstr only deals with con-apps, not with fun-apps or lambdas.
