[lldb-dev] unit testing C++ code in LLDB

[Todd Fiala]

I suspect there are only a handful of cases where I'd like to do this.
 Frankly I can even do it outside the source base proper, I suppose, but I
figured I'd throw the question out here since maybe this is something we
care about longer term.  I'm not really interested in hitting the app at
multiple layers for everything --- the existing python framework is great
for most things.  It's just for some niggly details on lower level pieces
of code that I care about it.

I may fiddle with it a bit.  If it looks gnarly in the end, I won't push it
further.  If it looks reasonable, I may throw up a patch to look at.
