Improve debug info printing with depth (#5903)

Skip repeated identical debug info only of more-nested nodes. Before this PR we
skipped sibling nodes and even parent nodes, which could be confusing. After
this PR there is a more clear connection: child nodes have the same debug location
as the parent, by default, and so there is no need to print it again.
