Add an assert that checks whether liveins are up to date before they are used. - Do not print liveins into .mir files anymore in situations where they are out of date anyway. - The assert in the RegisterScavenger is superseded by the new one in livein_begin(). - Skip parts of the liveness updating logic in IfConversion.cpp when liveness isn't tracked anymore (just enough to avoid hitting the new assert()).
