Move Void to GHC.Base...

This change would allow `Void` to be used deeper in module graph.
For example exported from `Prelude` (though that might be already
possible).

Also this change includes a change `stimes @Void _ x = x`,
https://github.com/haskell/core-libraries-committee/issues/95

While the above is not required, maintaining old stimes behavior
would be tricky as `GHC.Base` doesn't know about `Num` or `Integral`,
which would require more hs-boot files.

Add Javascript backend

Add JS backend adapted from the GHCJS project by Luite Stegeman.

Some features haven't been ported or implemented yet. Tests for these
features have been disabled with an associated gitlab ticket.

Refactor TyCon to have a top-level product

This patch changes the representation of TyCon so that it has
a top-level product type, with a field that gives the details
(newtype, type family etc), #22458.

Not much change in allocation, but execution seems to be a bit
faster.

Includes a change to the haddock submodule to adjust for API changes.

Add a missing varToCoreExpr in etaBodyForJoinPoint

This subtle bug showed up when compiling a library with 9.4.
See #22491.  The bug is present in master, but it is hard to
trigger; the new regression test T22491 fails in 9.4.

The fix was easy: just add a missing varToCoreExpr in
etaBodyForJoinPoint.

The fix is definitely right though!

I also did some other minor refatoring:
* Moved the preInlineUnconditionally test in simplExprF1 to
  before the call to joinPointBinding_maybe, to avoid fruitless
  eta-expansion.
* Added a boolean from_lam flag to simplNonRecE, to avoid two
  fruitless tests, and commented it a bit better.

These refactorings seem to save 0.1% on compile-time allocation in
perf/compiler; with a max saving of 1.4% in T9961

Metric Decrease:
    T9961

DmdAnal: Reflect the `seq` of strict fields of a DataCon worker (#22475)

See the updated `Note [Data-con worker strictness]`
and the new `Note [Demand transformer for data constructors]`.

Fixes #22475.
