Yes, I was too optimistic: the patch fixes //"Multiple connected components in live interval"// issues in `AMDGPU/*` tests but reveals next issue related to incorrect updates of ranges.
Regarding `Hexagon/expand-condsets-def-undef.mir` test issue - it is steel about multiple connected components.

Investigating these cases further.
