Revised how pass works, can now move code under 2 separate conditions:
- speculability -> works same as before
- memory effects —> requires loop to be LIVE based on current available methods

Other changes:
- read before writes within the same op but on separate resources are now allowed if the read resource is not in conflict
- test cases cleaned and provide more context
