0c681550 - [llvm-jitlink] Fix llvm-jitlink for LLVM_ENABLE_THREADS=Off.

[llvm-jitlink] Fix llvm-jitlink for LLVM_ENABLE_THREADS=Off. Commit edca1d9bad2 enabled threaded linking by default in llvm-jitlink, but we need to handle the case where LLVM is built with -DLLVM_ENABLE_THREADS=Off. This patch updates the llvm-jitlink tool to switch back to materialization on the main thread (equivalent to llvm-jitlink -num-threads=0 ...) when LLVM is built without thread support.
