[llvm] [ORC] Fix -Wunused-function warning on windows (PR #166207)

[Justin Bogner via llvm-commits]

https://github.com/bogner created https://github.com/llvm/llvm-project/pull/166207

All of the users of this function are guarded by LLVM_ON_UNIX and LLVM_ENABLE_THREADS ifdefs, so wrap the function itself in these guards as well to avoid the unused function warning.
