  ci: only push perf notes on master/release branches
  
  This patch fixes push_perf_notes logic in ci.sh to only push perf
  notes on master/release branches. We used to unconditionally push perf
  notes even in MRs, but the perf numbers in the wip branches wouldn't
  be used as baseline anyway, plus this is causing a space leak in the
  ghc-performance-notes repo. See #25317 for the perf notes repo size
  problem.

  Migrating the simplest types required for Trees That Grow progress
  from GHC.Types.Basic to Language.Haskell.Syntax.Basic. Related
  function definitions were also moved. Outputable type-class instances
   are defined in GHC.Utils.Outputable. Binary instance of Boxity was
  moved to GHC.Utils.Binary.
  
  Migrated types:
    * TopLevelFlag
    * RuleName
    * TyConFlavour
    * TypeOrData
    * NewOrData
