Research direction
Explore the 'Merovius/go tools' tool (specifically the 'redundantbranch' checker) and run it against the TiDB codebase. Identify files with useless branch control (e.g., redundant if else). Each instance should be evaluated and simplified. Pay attention to any discussions in the issue comments (currently only one comment) for guidance.
