0149d26adb * in PeepHoleOptPass1Cpu when an instruction contains a segment, don't replace the current instruction with the next, cause then we get an infinite loop when compiling on Win32 with -dTEST_WIN32_SEH -O4

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      optimizer that has since been superseded by the jump optimisations over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).
