New Revision: 141315

URL: http://llvm.org/viewvc/llvm-project?rev=141315&view=rev
Log:
Fix List-of-List Processing

Fix VarListElementInit::resolveListElementReference to return a
partially resolved VarListElementInint in the case where full
resolution is not possible.  This allows TableGen to make forward
progress resolving certain complex list expressions.
