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).

af107ca8fe o patch by J. Gareth Moreton, resolves #36355 
+ This patch serves to extend the JMP -> RET optimisation in OptPass2JMP by also doing the same
      for JMP -> MOV/RET, since there are often cases where the result (e.g. EAX) is set just
      prior to the function exiting.
    * RemoveDeadCodeAfterJump will now drop out if it detects SEH information -
      this stops exception information from being stripped if it is called on the final RET instruction.

c6116258fd o patch by J. Gareth Moreton: 
* adds an extra optimisation to "PostPeepholeOptMov" in compiler/x86/aoptx86.pas:
      If the instruction "MOV REG, -1" (Intel notation) is found, where REG is either
      a 32- or 64-bit register, it is changed to "OR REG, -1" instead.
      The effect is the same and takes exactly the same speed to execute, but the encoding is much smaller.
      As it cause false data dependencies, it is only applied in -Os mode

      For 16-bit registers, only AX is optimised this way because it has its own encoding for OR that takes fewer bytes.

dea1855126 o patch by J. Gareth Moreton, resolves #36352: 
* The supplied patch cleans up some vestigial code from the i386 peephole
      optimizer that has since been superseded by the jump optimisations over
      at #36271.
    * The PrePeepholeOptsCPU method has had a minor restructuring to better
      handle the rare case where InsContainsSegRef() returns True and
      p becomes something that is no longer an instruction (it ultimately
      removes a conditonal check and some overhead from repeated function calls).
