Re-apply r80926, with fixes: keep the domtree informed of new blocks
...
that get created during loop unswitching, and fix SplitBlockPredecessors'
LCSSA updating code to create new PHIs instead of trying to just move
existing ones.
Also, optimize Loop::verifyLoop, since it gets called a lot. Use
searches on a sorted list of blocks instead of calling the "contains"
function, as is done in other places in the Loop class, since "contains"
does a linear search. Also, don't call verifyLoop from LoopSimplify or
LCSSA, as the PassManager is already calling verifyLoop as part of
LoopInfo's verifyAnalysis.

More migration to raw_ostream, the water has dried up around the iostream hole.

- Some clients which used DOUT have moved to DEBUG. We are deprecating the

downside of leaving code in -Asserts builds, and of hiding potentially
unnecessary computations.
