lawrence_danna created this revision.
lawrence_danna added reviewers: JDevlieghere, jasonmolenda, labath.
Herald added a project: LLDB.
lawrence_danna added a parent revision: D68188: allow arbitrary python streams 
to be converted to SBFile.

It's really annoying and confusing to have to keep referring
back to earlier versions of this SBFile work to find the
tests that need to be added for each patch, and not duplicate
them with new tests.

This patch just imports all my tests.   A bunch of them don't
work yet, so they are marked to be skipped.   They'll be
unmarked as I fix them.

One of these tests will actually trip an assert in the SWIG
code now instead of just failing, so I'm fixing that here too.
