[PATCH] D159406: [SelectionDAG] Generalise SelectionDAG::computeOverflowKind to support other opcodes

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

I'd recommend starting with removing the existing code at the bottom of visitMULO that handles SMULO/UMULO -> MUL conversion and replacing it with a willNotOverflowMul check.
