[PATCH] Revert "[PECOFF] Add atoms to the PassManager file"

[Shankar Kalpathi Easwaran]

  You may want to look a the ELF passes in X86_64/Hexagon, what they do is add to a vector of all atoms that you want to add to the PassManager file and set Ordinals.

  By the way, where are ordinals set here ?
