LOG: [LLVM]Fix symbol visibility macros not being define for AIX (#107705)

This is to try and fix buildbot failure on
[clang-ppc64-aix](https://lab.llvm.org/buildbot/#/builders/64/builds/881)
from my changes in #96630. I don't really know much about AIX so it
would be good to have someone more knowledgeable to say if visibility
macros on extern templates is needed on AIX similar to ELF. @compnerd
