For historical reasons, temp was returning a copy of the created Node*, not the original Node*. This meant that if analysis recorded information in the returned node (for example, n->addrtaken = 1), the analysis would not show up on the original Node*, the one kept in fn->dcl and consulted during liveness bitmap creation. Correct this, and watch for it when setting addrtaken. Fixes #7083. R=khr, dave, minux.ma CC=golang-codereviews https://golang.org/cl/51010045
