Remove LCSSA's bogus dependence on LoopSimplify and LoopSimplify's bogus
...
dependence on DominanceFrontier. Instead, add an explicit DominanceFrontier
pass in StandardPasses.h to ensure that it gets scheduled at the right
time.
Declare that loop unrolling preserves ScalarEvolution, and shuffle some
getAnalysisUsages.
This eliminates one LoopSimplify and one LCCSA run in the standard
compile opts sequence.

compute a set of reachable blocks for itself each time it is called, which
is fairly frequently.
