JDK-8313616 added the support of loading library members on AIX in os::dll_load in JDK 22.   On AIX, is a shared object a member object loaded from `libname.a(libname.so)`?   If so, changing `mapLibraryName` implementation seems to be a proper fix.   If you want to load a specific version, it should call `loadLibrary("libclang.a(libclang.so.16)")` instead.

As @jaikiran suggests, `loadLibraryOnlyIfPresent()` should return false for AIX as the file does not exist.   The library implementation may need to adjust as the current implementation uses a file path name.
