0a68a9d6 - [clang][AIX] Fix -print-runtime-dir fallback on AIX (#141439)

[clang][AIX] Fix -print-runtime-dir fallback on AIX (#141439) If the runtime path is not found (by getTargetSubDirPath()), since per target runtime directory is enabled on AIX, we should fall back to the target subdirectory rather than the OS subdirectory.
