revert: move manifest membership condition outside of the loop

Currently, revset is using information from dirstate status and alter its
behavior whenever the file exist in the target manifest or not. This tests are
done a big for loop. We move this member ship testing outside of the loop and
simplifies associates data structure.

This is a step toward a cleaner implementation of revert based on status.
