Jakob Stoklund Olesen fe9b2d142a Fix bug in SplitEditor::splitLiveThroughBlock when switching registers.
If there is no interference and no last split point, we cannot
enterIntvBefore(Stop) - that function needs a real instruction.

Use enterIntvAtEnd instead for that very easy case.

This code doesn't currently run, it is needed by multi-way splitting.
