So, I take a look at this to reply to your question. They're all flakey.
Most of them fails non-deterministically depending on the load of the system. I just wrote a driver that spawns randomly threads that spin loops & checked out multiple copies of lldb and ran test suites in parallel.
I see many of the failures testing completion randomly failing.
