  VT: teach isImpliedCondOperands about samesign (#120263)

isImpliedCondICmps() and its callers in ValueTracking can greatly
benefit from being taught about samesign. As a first step, teach one
caller, namely isImpliedCondOperands(). Very minimal changes are
required for this, as CmpPredicate::getMatching() does most of the work.
