rts: don't enforce aligned((8)) on 32-bit targets
We simply need to align to the word size for pointer tagging to work. On
32-bit targets, aligned((8)) is wasteful.

Export symbolSing, SSymbol, and friends (CLC#85)
This implements this Core Libraries Proposal:
https://github.com/haskell/core-libraries-committee/issues/85
In particular, it:
1. Exposes the `symbolSing` method of `KnownSymbol`,
2. Exports the abstract `SSymbol` type used in `symbolSing`, and
3. Defines an API for interacting with `SSymbol`.
This also makes corresponding changes for `natSing`/`KnownNat`/`SNat` and
`charSing`/`KnownChar`/`SChar`. This fixes #15183 and addresses part (2)
of #21568.

Parser/PostProcess: rename failOp* functions
There are three functions named failOp* in the parser:
failOpNotEnabledImportQualifiedPost
failOpImportQualifiedTwice
failOpFewArgs
Only the last one has anything to do with operators. The other two
were named this way either by mistake or due to a misunderstanding of
what "op" stands for. This small patch corrects this.

Make rewrite rules "win" over inlining
If a rewrite rule and a rewrite rule compete in the simplifier, this
patch makes sure that the rewrite rule "win". That is, in general
a bit fragile, but it's a huge help when making specialisation work
reliably, as #21851 and #22097 showed.
The change is fairly straightforwad, and documented in
Note [Rewrite rules and inlining]
in GHC.Core.Opt.Simplify.Iteration.
Compile-times change, up and down a bit -- in some cases because
we get better specialisation. But the payoff (more reliable
specialisation) is large.

There are extensive notes in !8897 about the regressions.
Briefly
* fibheaps: there was a very delicately balanced inlining that
tipped over the wrong way after this change.
* cryptarithm2 and paraffins are caused by #22274, which is
a separate issue really. (I.e. the right fix is *not* to
make inlining "win" over rules.)
So I'm accepting these changes

Utils.JSON: do not escapeJsonString in ToJson String instance
as `escapeJsonString` is used in `renderJSON`, so the `JSString`
constructor is meant to carry the unescaped string.

Make Cmm Lint messages use dump style
Lint errors indicate an internal error in GHC, so it makes sense to use
it instead of the user style. This is consistent with Core Lint and STG Lint:
https://gitlab.haskell.org/ghc/ghc/-/blob/22096652/compiler/GHC/Core/Lint.hs#L429
https://gitlab.haskell.org/ghc/ghc/-/blob/22096652/compiler/GHC/Stg/Lint.hs#L144
Fixes #22218.
