[PATCH] D136753: [DemandedBits] Add Div instruction to DetermineLiveOperandBits

[Tim Northover via Phabricator via llvm-commits]

t.p.northover added a comment.

I don't think this is how division works. It mixes bits up far more than add/sub/mul for which a bit in the input can only affect equal or lower ones in the output.
