7e6eeebdf0 o patch by J. Gareth Moreton, seeks to improve maintainability, safety and efficiency 
in the peephole optimizer by slightly modifying some function headers based
    on their intended purpose, resolves #36353
    * Non-virtual methods and class methods that don't need to access any fields from
      the current object are now static methods, thus removing the hidden "Self"
      parameter and reducing overhead. This includes a large number of
      frequently-used functions such as SkipEntryExitMarker and SuperRegistersEqual.
    * GetNextInstruction, GetLastInstruction, SkipEntryExitMarker and
      SkipLabels have had their 'var' parameter changed to an 'out' parameter because
      they shouldn't depend on its input value. This will cause the compiler to throw warnings
      if you start using the value without initialising it first, and may open up optimisation
      opportunities in the future (e.g. storing written values in a temporary register
      and only writing it to the actual variable when the routine exits).
