  Log Message:
  -----------
  [PassInstrumentation] Don't insert extra entries in getPassNameForClassName (#150029)

Don't modify ClassToPassName map unless ClassName is found. Instead,
just return empty StringRef if there is no matching entry. This will
prevent possible dangling references in ClassToPassName map in case of
ClassName being freed.
See https://github.com/llvm/llvm-project/pull/145059/files#r2219763671
