River Riddle 2b61b7979e Convert the Canonicalize and CSE passes to generic Operation Passes. 
This allows for them to be used on other non-function, or even other function-like, operations. The algorithms are already generic, so this is simply changing the derived pass type. The majority of this change is just ensuring that the nesting of these passes remains the same, as the pass manager won't auto-nest them anymore.
