Duncan P. N. Exon Smith 9437b219c2 ValueMapper: Resolve cycles on the new nodes ... Fix a major bug from r265456. Although it's now much rarer, ValueMapper sometimes has to duplicate cycles. The might-transitively-reference-a-temporary counts don't decrement on their own when there are cycles, and you need to call MDNode::resolveCycles to fix it. r265456 was checking the input nodes to see if they were unresolved. This is useless; they should never be unresolved. Instead we should check the output nodes and resolve cycles on them. llvm-svn: 266258		2016-04-13 22:54:01 +00:00
