Matthias Braun 311730ac78 LiveIntervalAnalysis: Factor out code to update liveness on vreg def removal ...

This cleans up code and is more in line with the general philosophy of
modifying LiveIntervals through LiveIntervalAnalysis instead of changing
them directly.

This also fixes a case where SplitEditor::removeBackCopies() would miss
the subregister ranges.
