  Word64Map: add compareSize
  
  compareSize m c compares the size of a map to an Int, but unlike
  compare (size m) c it stops traversing the map once the outcome is
  determined.
  
  Based on https://github.com/haskell/containers/pull/1139

  Use a pigeonhole sort for deterministic UniqDFM iteration
  
  Deterministic UniqDFM iteration used a list mergesort, allocating O(n
  log n) cons cells and contributing significantly to compiler allocations
  (#27459).
  
  Use a pigeonhole sort where appropriate, while retaining the mergesort
  fallback. See Note [Sorting a UDFM] and Note [Cost of deterministic
  iteration].
  
  The peak_megabytes_allocated increase for LinkableUsage02 is probably
  due to GC timing noise. See #27613.

  Testsuite: don't measure max residency for T27336
  
  We really care more about total allocations for this test, so this commit
  removes the maximum residency measurement.

  hie.yaml: use a polyglot shell/batch script
  
  This commit merges hie-bios and hie-bios.bat into a single polyglot
  script. This avoids Windows users having to manually update hie.yaml
  in order to be able to use HLS.

  EPA: Remove type parameter from AnnList
  
  This is a step towards cutting AnnList down to its core for formatting
  lists only
