  [libc] Fix hanging test on NVPTX due to lack of warp sync

Previously this wasn't implemented because it's effectively a no-op.
However, this should be safe to emit on sm_60 architectures. It's
important because it carries semantic importance for whether or not
something can be moved. So we should always emit this instrinsic.
