[PATCH] [PECOFF] Do not use layout-after/before relationships for grouped sections.

[Shankar Kalpathi Easwaran]

  We group atoms by type and permissions so that we get the same results from sort at all times. This is mainly used in targets which dont use layout after and layout before references by default too.

  Order by section position is important because targets may desire to position certain atoms at the start and end of each section.

  I totally agree, finding the first and last atom or even finding if there is a layout after / layout before reference, is not optimized currently for speed, but it would eventually be after all the functionalities are made complete.
