Make LCSSA insert proper Phi nodes throughout the rest of the CFG by computing
...
the iterated Dominance Frontier of the loop-closure Phi's. This is the
second phase of the LCSSA pass. The third phase (coming soon) will be to
update all uses of loop variables to use the loop-closure Phi's instead.

Clean up and refactor LCSSA a bunch. It should also run faster now, though

there's still a lot of work to be done on it.
