[PATCH] D59119: [SelectionDAG] Check legality for ADDCARRY in expandMUL_LOHI

[Eli Friedman via Phabricator via llvm-commits]

I'm not sure what you're hoping to accomplish with this change.  Even on targets where i64 ADDCARRY isn't legal, we have code to expand it (see DAGTypeLegalizer::ExpandIntRes_ADDSUBCARRY etc.), and it's still generally cheap.
