clearing the map ended up calling back into the TypeSystemMap to do lookups. Not a good idea, and in this case it would cause a deadlock. You would only see this when replacing the target contents after an exec, and only if you had stopped before the exec, evaluated an expression, then continued on to the point where you did the exec. Fixed this by making sure the TypeSystemMap::Clear tears down the TypeSystems in the map before clearing the map. I also add an expression before exec to the TestExec.py so that we'll catch this issue if it crops up again in the future. <rdar://problem/24554920> llvm-svn: 260624
