[PATCH] D29252: [NewGVN] Update dominator tree for unreachable blocks.

[Daniel Berlin via Phabricator via llvm-commits]

dberlin added a comment.

For now i think we should revert the original change and insert the store, unless someone has evidence that doing something else produces actual performance improvement, instead of just looking nicer

We can always burn this bridge again when we come to it.
