[PATCH] D112016: [IR] Introduce load assume operand bundle

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

Aside from the cost modeling, I think there is value in having a more compact representation for this concept. It is nice to be able to turn four instructions (cast, load, icmp, assume) into one (assume). OK, maybe opaque pointers will remove the cast, but the point stands. This feature also has applications besides C++ devirtualization, so I think it's worth the added maintenance cost.
