[llvm] [DebugInfo][test] Remove irrelevant problematic lines. (PR #177691)

Does this actively cause a fault / expose a bug in LLVM today? I'm all in favour of refining the CFI implementation, but removing information from a test is reducing coverage, and doing so is best done as part of a well-contained change / patch series. That way we can reason about what coverage is lost/gained as part of the code revision process.
