LOG: Remove analysis preservations subsumed by CFG preservation. NFC (#212672)
Legacy PM: setPreservesCFG() adds every pass registered as CFG-only
(dominator/post-dominator trees, loop/cycle info, block frequency,
register class info, BasicAA, ...) to the preserved set, so a separate
addPreserved<X> for such X is a no-op, as is
addPreservedID(MachineDominatorsID) / addPreservedID(MachineLoopInfoID).
New PM: preserveSet<CFGAnalyses>() keeps every result whose invalidate()
accepts the CFGAnalyses set, making an explicit preserve<X>() on the
same PreservedAnalyses redundant. SLPVectorizer, AggressiveInstCombine
and SROA keep their explicit preserves, which are load-bearing on paths
that change the CFG.
