[ValueTracking] Use ConstantRange methods; NFC

Switch part of the computeOverflowForSignedAdd() implementation to
use Range.isAllNegative() rather than KnownBits.isNegative() and
similar. They do the same thing, but using the ConstantRange methods
allows dropping the KnownBits variables more easily in D60420.
