Account for local rules in specImports
As #23024 showed, in GHC.Core.Opt.Specialise.specImports, we were
generating specialisations (a locally-define function) for imported
functions; and then generating specialisations for those
locally-defined functions. The RULE for the latter should be
attached to the local Id, not put in the rules-for-imported-ids
set.
Fix is easy; similar to what happens in GHC.HsToCore.addExportFlagsAndRules

JS: fix for overlap with copyMutableByteArray# (#23033)
The code wasn't taking into account some kind of overlap.
cgrun070 has been extended to test the missing case.

Take more care with unlifted bindings in the specialiser
As #22998 showed, we were floating an unlifted binding to top
level, which breaks a Core invariant.
The fix is easy, albeit a little bit conservative. See
Note [Care with unlifted bindings] in GHC.Core.Opt.Specialise

Account for TYPE vs CONSTRAINT in mkSelCo
As #23018 showed, in mkRuntimeRepCo we need to account for coercions
between TYPE and COERCION.
See Note [mkRuntimeRepCo] in GHC.Core.Coercion.

hadrian: Add dependency from lib/settings to mk/config.mk
In 81975ef375de07a0ea5a69596b2077d7f5959182 we attempted to fix #20253
by adding logic to the bindist Makefile to regenerate the `settings`
file from information gleaned by the bindist `configure` script.
However, this fix had no effect as `lib/settings` is shipped in the
binary distribution (to allow in-place use of the binary distribution).
As `lib/settings` already existed and its rule declared no dependencies,
`make` would fail to use the added rule to regenerate it.
Fix this by explicitly declaring a dependency from `lib/settings` on
`mk/config.mk`.
Fixes #22982.

Revert the main payload of "Make `drop` and `dropWhile` fuse (#18964)"
This reverts the bits affecting fusion of `drop` and `dropWhile` of commit
0f7588b5df1fc7a58d8202761bf1501447e48914 and keeps just the small refactoring
unifying `flipSeqTake` and `flipSeqScanl'` into `flipSeq`.
It also adds a new test for #23021 (which was the reason for reverting) as
well as adds a clarifying comment to T18964.
Fixes #23021, unfixes #18964.
Metric Increase:
T18964
Metric Decrease:

Refine the test for naughty record selectors
The test for naughtiness in record selectors is surprisingly subtle.
See the revised Note [Naughty record selectors] in GHC.Tc.TyCl.Utils.
Fixes #23038.

Don't suppress *all* Wanteds
Code in GHC.Tc.Errors.reportWanteds suppresses a Wanted if its
rewriters have unfilled coercion holes; see
Note [Wanteds rewrite Wanteds] in GHC.Tc.Types.Constraint.
But if we thereby suppress *all* errors that's really confusing,
and as #22707 shows, GHC goes on without even realising that the
program is broken. Disaster.
This MR arranges to un-suppress them all if they all get suppressed.
Close #22707

Check for platform support for JavaScript foreign imports
GHC was accepting `foreign import javascript` declarations
on non-JavaScript platforms. This adds a check so that these
are only supported on an platform that supports the JavaScript
calling convention.
Fixes #22774

rts: Statically assert alignment of Capability
In #22965 we noticed that changes in the size of `Capability` can result
in unsound behavior due to the `align` pragma claiming an alignment
which we don't in practice observe. Avoid this by statically asserting
that the size is a multiple of the alignment.

to be aligned, resulting in #22965.

the same favorable alignment on Windows that we provided on other
platforms. Fix this.

constant folding: Correct type of decodeDouble_Int64 rule
The first argument is Int64# unconditionally, so we better produce
something of that type. This fixes a core lint error found in the ad
package.

ncg/aarch64: Handle MULTILINE_COMMENT identically as COMMENTs
Commit 7566fd9de38c67360c090f828923d41587af519c with the fix for #22798 was
incomplete as it failed to handle MULTILINE_COMMENT pseudo-instructions, and
didn't completly fix the compiler panics when compiling with `-fregs-graph`.

More fixes for `type data` declarations
This MR fixes #23022 and #23023. Specifically
* Beef up Note [Type data declarations] in GHC.Rename.Module,
to make invariant (I1) explicit, and to name the several
wrinkles.
And add references to these specific wrinkles.
* Add a Lint check for invariant (I1) above.
See GHC.Core.Lint.checkTypeDataConOcc
* Disable the `caseRules` for dataToTag# for `type data` values.
See Wrinkle (W2c) in the Note above. Fixes #23023.
* Refine the assertion in dataConRepArgTys, so that it does not
complain about the absence of a wrapper for a `type data` constructor
Fixes #23022.

Try to create somewhat portable `ld` command
I cannot figure out a good way to generate an `ld` command
that works on both Linux and macOS. Normally you'd use something
like `AC_LINK_IFELSE` for this purpose (I think), but that won't
let us test response file support.

Convert diagnostics in GHC.Rename.Module to proper TcRnMessage (#20115)
I've turned almost all occurrences of TcRnUnknownMessage in GHC.Rename.Module
module into a proper TcRnMessage.
Instead, these TcRnMessage messages were introduced:
TcRnIllegalInstanceHeadDecl
TcRnUnexpectedStandaloneDerivingDecl
TcRnUnusedVariableInRuleDecl
TcRnUnexpectedStandaloneKindSig
TcRnIllegalRuleLhs
TcRnBadAssocRhs
TcRnDuplicateRoleAnnot
TcRnDuplicateKindSig
TcRnIllegalDerivStrategy
TcRnIllegalMultipleDerivClauses
TcRnNoDerivStratSpecified
TcRnStupidThetaInGadt
TcRnBadImplicitSplice
TcRnShadowedTyVarNameInFamResult
TcRnIncorrectTyVarOnLhsOfInjCond
TcRnUnknownTyVarsOnRhsOfInjCond
Was introduced one helper type:

Constraint simplification loop now depends on `ExpansionFuel`
instead of a boolean flag for `CDictCan.cc_pend_sc`.
Pending givens get a fuel of 3 while Wanted and quantified constraints get a fuel of 1.
This helps pending given constraints to keep up with pending wanted constraints in case of
`UndecidableSuperClasses` and superclass expansions while simplifying the infered type.
Adds 3 dynamic flags for controlling the fuels for each type of constraints
`-fgivens-expansion-fuel` for givens `-fwanteds-expansion-fuel` for wanteds and `-fqcs-expansion-fuel` for quantified constraints
Fixes #21909
Added Tests T21909, T21909b
