JS: establish single source of truth for symbols
In pursuit of: #22736.
This MR moves ad-hoc symbols used throughout the js backend into a
single symbols file. Why? First, this cleans up the code by removing
ad-hoc strings created on the fly and therefore makes the code more
maintainable. Second, it makes it much easier to eventually type these
identifiers.

rts: replace ad-hoc MYTASK_USE_TLV with proper CC_SUPPORTS_TLS
This patch replaces the ad-hoc `MYTASK_USE_TLV` with the
`CC_SUPPORTS_TLS` macro. If TLS support is detected by autoconf, then
we should use that for managing `myTask` in the threaded RTS.

Add `__GLASGOW_HASKELL_ASSERTS_IGNORED__` as CPP macro name if `-fasserts-ignored is set.
This allows users to create their own Control.Exception.assert-like functionality that
does something other than raising an `AssertFailed` exception.

Fix a QuickLook bug
This MR fixes the bug exposed by #24676. The problem was that
quickLookArg was trying to avoid calling tcInstFun unnecessarily; but
it was in fact necessary. But that in turn forced me into a
significant refactoring, putting more fields into EValArgQL.
Highlights: see Note [Quick Look overview] in GHC.Tc.Gen.App
* Instantiation variables are now distinguishable from ordinary
unification variables, by level number = QLInstVar. This is
treated like "level infinity". See Note [The QLInstVar TcLevel]
in GHC.Tc.Utils.TcType.
* In `tcApp`, we don't track the instantiation variables in a set Delta
any more; instead, we just tell them apart by their level number.
* EValArgQL now much more clearly captures the "half-done" state
of typechecking an argument, ready for later resumption.
See Note [Quick Look at value arguments] in GHC.Tc.Gen.App
* Elminated a bogus (never used) fast-path in
GHC.Tc.Utils.Instantiate.instCallConstraints
See Note [Possible fast path for equality constraints]
Many other small refactorings.

haddock: Fix hyperlinker source urls (#24907)
This fixes a bug introduced by f56838c36235febb224107fa62334ebfe9941aba Links to
external modules in the hyperlinker are uniformly generated using splicing the
template given to us instead of attempting to construct the url in an ad-hoc manner.

Prioritise nominal equalities
The main payload of this patch is
* Prioritise nominal equalities in the constraint solver. This
ameliorates the incompleteness of solving for representational
constraints over newtypes: see #24887.
See (EX2) in Note [Decomposing newtype equalities] in
GHC.Tc.Solver.Equality
In doing this patch I tripped over some other things that I refactored:
* Move `isCoVarType` from `GHC.Core.Type` to `GHC.Core.Predicate`
where it seems more at home.
* Clarify the "rewrite role" of a constraint. I was very puzzled
about what the role of, say `(Eq a)` might be, but see the new
Note [The rewrite-role of a constraint].
In doing so I made predTypeEqRel crash when given a non-equality.
Usually it expects an equality; but it was being mis-used for
the above rewrite-role stuff.

rts: use page sized mblocks on wasm

Various fixes to type-tidying
This MR was triggered by #24868, but I found a number of bugs
and infelicities in type-tidying as I went along. Highlights:
* Fix to #24868 is in GHC.Tc.Errors.report_unsolved: avoid
using the OccNames of /bound/ variables when tidying /free/
variables; see the call to `tidyAvoiding`. That avoid the
gratuitous renaming which was the cause of #24868. See
Note [tidyAvoiding] in GHC.Core.TyCo.Tidy
* Refactor and document the tidying of open types.
See GHC.Core.TyCo.Tidy
Note [Tidying open types]
Note [Tidying is idempotent]
* Tidy the coercion variable in HoleCo. That's important so
that tidied types have tidied kinds.
* Some small renaming to make things consistent. In particular
the "X" forms return a new TidyEnv. E.g.
tidyOpenType :: TidyEnv -> Type -> Type
tidyOpenTypeX :: TidyEnv -> Type -> (TidyEnv, Type)

compiler: Rejects RULES whose LHS immediately fails to type-check
Fixes GHC crashing on `decomposeRuleLhs` due to ignoring coercion values. This
happens when we have a RULE that does not type check, and enable
`-fdefer-type-errors`. We prevent this to happen by rejecting RULES with an
immediately LHS type error.

in future versions of HLS.

Progress towards #21592
Specificity, ForAllTyFlag and its' helper functions are extracted from

Note: Eventually (i.e. after Language.Haskell.Syntax.Decls does not depend on
GHC.* anymore) these should be moved into Language.Haskell.Syntax.Decls.
At this point, this would cause cyclic dependencies.

ttg: Split HsSrcBang, remove ref to DataCon from Syntax.Type
Progress towards #21592
This splits HsSrcBang up, creating the new HsBang within
`Language.Haskell.Syntax.Basic`. `HsBang` holds the unpackedness
and strictness information, while `HsSrcBang` only adds the SourceText
for usage within the compiler directly.
Inside the AST, to preserve the SourceText, it is hidden behind the
pre-existing extension point `XBindTy`. All other occurrences of
`HsSrcBang` were adapted to deconstruct the inner `HsBang`, and when
interacting with the `BindTy` constructor, the hidden `SourceText` is
extracted/inserted into the `XBindTy` extension point.
`GHC.Core.DataCon` exports both `HsSrcBang` and `HsBang` for
convenience. A constructor function `mkHsSrcBang` that takes all
individual components has been added.
Two exceptions has been made though:
- The `Outputable HsSrcBang` instance is replaced by
`Outputable HsBang`. While being only GHC-internal, the only place
it's used is in outputting `HsBangTy` constructors -- which already
have `HsBang`. It wouldn't make sense to reconstruct a `HsSrcBang` just
to ignore the `SourceText` anyway.
- The error `TcRnUnexpectedAnnotation` did not use the `SourceText`,
so it too now only holds a `HsBang`.
