  [SCEV][NFC] Move check up the stack

One of (and primary) callers of isBasicBlockEntryGuardedByCond is
isKnownPredicateAt, which makes isKnownPredicate check before it.
It already makes non-recursive check inside. So, on this execution
path this check is made twice. The only other caller is
isLoopEntryGuardedByCond. Moving the check there should save some
compile time.
