Bjorn Pettersson d30f308a9f Add support for computing "zext of value" in KnownBits. NFCI ... Summary: The description of KnownBits::zext() and KnownBits::zextOrTrunc() has confusingly been telling that the operation is equivalent to zero extending the value we're tracking. That has not been true, instead the user has been forced to explicitly set the extended bits as known zero afterwards. This patch adds a second argument to KnownBits::zext() and KnownBits::zextOrTrunc() to control if the extended bits should be considered as known zero or as unknown.
