Fix #22459, in two ways:
(1) Make the Specialiser not create a bogus specialisation if
it is presented by strangely polymorphic dictionary.
See Note [Weird special case in SpecDict] in
GHC.Core.Opt.Specialise
(2) Be more careful in abstractFloats
See Note [Which type variables to abstract over]
in GHC.Core.Opt.Simplify.Utils.
So (2) stops creating the excessively polymorphic dictionary in
abstractFloats, while (1) stops crashing if some other pass should
nevertheless create a weirdly polymorphic dictionary.

Issue #22623 demonstrated another lacuna in the implementation
of wrinkle (BS3) in Note [The binder-swap substitution] in
the occurrence analyser.
I was failing to add TyVar lambda binders using
addInScope/addOneInScope and that led to a totally bogus binder-swap
transformation.
Very easy to fix.
