Alina Sbirlea 80c6e79602 [MemorySSA] LoopSimplify preserves MemorySSA only when flag is flipped. 
LoopSimplify can preserve MemorySSA after r360270.
But the MemorySSA analysis is retrieved and preserved only when the
EnableMSSALoopDependency is set to true. Use the same conditional to
mark the pass as preserved, otherwise subsequent passes will get an
invalid analysis.
Resolves PR41853.
