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.

It seems we reserve 8 registers instead of four for global regs

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

Also migrate Fixity from GHC.Hs to Language.Haskell.Syntax

Remove mkOpFormRn, it is also dead code, only used in the arrow
desugaring now removed.
