Duncan P. N. Exon Smith f067a68207 IR: Enable uniquing callbacks during MDNode::replaceWithUniqued() ... Uniqued nodes have more complete registration with `ReplaceableMetadataImpl` so that they can update themselves when operands change. Fix a bug where `MDNode::replaceWithUniqued()` wasn't enabling these callbacks. The two most obvious ways missing callbacks causes problems is that auto-resolution fails and re-uniquing (on changed operands) just doesn't happen. I've added tests for both -- in both cases, I confirmed that the final check was failing before the fix. rdar://problem/20365935 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233751 91177308-0d34-0410-b5e6-96231b3b80d8		2015-03-31 20:50:50 +00:00
