Revert "Allow non-absolute values for bootstrap GHC variable"

This broke configure in subtle ways resulting in #25076 where hadrian
didn't end up the boot compiler it was configured to use.

This reverts commit 209d09f52363b261b900cf042934ae1e81e2caa7.

Fix bad bug in mkSynonymTyCon, re forgetfulness

As #25094 showed, the previous tests for forgetfulness was
plain wrong, when there was a forgetful synonym in the RHS
of a synonym.

Define Eq1, Ord1, Show1 and Read1 instances for basic Generic representation types

This way the Generically1 newtype could be used to derive Eq1 and Ord1
for user types with DerivingVia.

The CLC proposal is https://github.com/haskell/core-libraries-committee/issues/273.

The GHC issue is https://gitlab.haskell.org/ghc/ghc/-/issues/24312.

Address #25055, by disabling case-of-runRW# in Gentle phase

See Note [Case-of-case and full laziness]

Fix -freg-graphs for FP and AARch64 NCG (#24941).

It seems we reserve 8 registers instead of four for global regs
based on the layout in Note [AArch64 Register assignments].

I'm not sure it's neccesary, but for now we just accept this state of
affairs and simple update -fregs-graph to account for this.

Fix nasty bug in occurrence analyser

As #25096 showed, the occurrence analyser was getting one-shot info
flat out wrong.

This commit does two things:

* It fixes the bug and actually makes the code a bit tidier too.
  The work is done in the new function
     GHC.Core.Opt.OccurAnal.mkRhsOccEnv,
  especially the bit that prepares the `occ_one_shots` for the RHS.

  See Note [The OccEnv for a right hand side]

* When floating out a binding we must be conservative about one-shot
  info.  But we were zapping the entire demand info, whereas we only
  really need zap the /top level/ cardinality.

  See Note [Floatifying demand info when floating]
  in GHC.Core.Opt.SetLevels

For some reason there is a 2.2% improvement in compile-time allocation
for CoOpt_Read.  Otherwise nickels and dimes.

Metric Decrease:
    CoOpt_Read

TTG HsCmdArrForm: use Fixity via extension point

Also migrate Fixity from GHC.Hs to Language.Haskell.Syntax
since it no longer uses any GHC-specific data types.

Fixed arrow desugaring bug. (This was dead code before.)
Remove mkOpFormRn, it is also dead code, only used in the arrow
desugaring now removed.
