These were changes are all triggered by #24471.
1. Make GHC.Core.Opt.SetLevels.lvlMFE behave better when there are
many free variables. See Note [Large free-variable sets].
2. Make GHC.Core.Opt.Arity.floatIn a bit lazier in its Cost argument.
This benefits the common case where the ArityType turns out to
be nullary. See Note [Care with nested expressions]
3. Make GHC.CoreToStg.Prep.cpeArg behave for deeply-nested
expressions. See Note [Eta expansion of arguments in CorePrep]
wrinkle (EA2).
Compile times go down by up to 4.5%, and much more in artificial
cases. (Geo mean of compiler/perf changes is -0.4%.)
