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.
