Max Kazantsev dd5ee6f5d9 [SCEV] Make isLoopEntryGuardedByCond a bit smarter 
Sometimes `isLoopEntryGuardedByCond` cannot prove predicate `a > b` directly.
But it is a common situation when `a >= b` is known from ranges and `a != b` is
known from a dominating condition. Thia patch teaches SCEV to sum these facts
together and prove strict comparison via non-strict one.
