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

[Shankar Easwaram]

It became more of a discussion post this revert as I was unclear on how the atom got inserted into the file twice and all tests were still passing. I think there is a lack of test otherwise this could have been caught earlier. 

We should add a test along with the revert to make sure the revert actually fixes something.
