[SplitKit] In addDeadDef tolerate parent range that defines more lanes
Following on from D87757 "[SplitKit] Only copy live lanes", in
SplitEditor::addDeadDef, when we're checking whether the parent live
interval has a subrange defining the same lanes, tolerate the case
where the parent subrange defines a superset of the lanes. This can
happen when the child subrange comes from SplitEditor::buildCopy
decomposing a partial copy into a sequence of subreg copies that cover
the required lanes.
