[SCEV] Clean up isKnownPredicateViaConstantRanges; NFCI
- ScalarEvolution::isKnownPredicateViaConstantRanges duplicates some
logic already present in ConstantRange, use ConstantRange for those
bits.
- In some cases ScalarEvolution::isKnownPredicateViaConstantRanges
returns `false` to mean "definitely false" (e.g. see the
`LHSRange.getSignedMin().sge(RHSRange.getSignedMax())` case for
`ICmpInst::ICMP_SLT`), but for `isKnownPredicateViaConstantRanges`,
`false` actually means "don't know". Get rid of this extra bit of
code to avoid confusion.
