  -----------
  [clang] Fix false positive regression for lifetime analysis warning. (#127460)

This fixes a false positive caused by #114044.

For `GSLPointer*` types, it's less clear whether the lifetime issue is
about the GSLPointer object itself or the owner it points to. To avoid
false positives, we take a conservative approach in our heuristic.

Fixes #127195

(This will be backported to release 20).

(cherry picked from commit 9c49b188b8e1434eb774ee8422124ad3e8870dce)
