  Log Message:
  -----------
  [llvm-jitlink] Use -num-threads=0 for regression tests relying on debug output.

ORC and JITLink debugging output write the dbgs() raw_ostream, which isn't
thread-safe. Use -num-threads=0 to force single-threaded linking for tests that
produce debugging output.

The llvm-jitlink tool is updated to suggest -num-threads=0 when debugging
output is enabled.
