I have pushed an update to optimize candidate scanning in `mergeCompatibleUnreachableCalls`.

In local CTMark testing, `.text` code size remains flat ($0.0\\%$ regression) and compile time improved by **$-0.8\\%$** geomean.

Could someone please help queue this PR on `llvm-compile-time-tracker` to verify the broader impact? Thanks!
