tests was added in r287105.

5e3cac3e57 On arm64 disable three tests that hang or panic
Each issue has a PR open to track. This workaround allows us to run the
tests to investigate the failures and avoid any new regressions.

41da933c87 Hook up support for userland CTF support in DTrace. This required some
modifications to libproc to support fetching the CTF info for a given file.

With this change, dtrace(1) is able to resolve type info for function and
USDT probe arguments, and function return values. In particular, the args[n]
syntax should now work for referencing arguments of userland probes,
provided that the requisite CTF info is available.

The uctf tests pass if the test programs are compiled with CTF info. The
current infrastructure around the DTrace test suite doesn't support this
yet.
