This revision is now accepted and ready to land.

Discussed this offline, and proposed this solution to make progress and resolve the failing tests.
This does need exploring further though as:

1. the behavior of current LSR will no longer be tested in the new pass manager, due to LCSSA being run as a canonicalization pass.
2. adding it to a loop pass manager in the npm will be problematic, because it doesn't preserve LCSSA.
