Keith Randall 8179b9b462 cmd/compile: make sure output params are live if there is a defer ... If there is a defer, and that defer recovers, then the caller can see all of the output parameters. That means that we must mark all the output parameters live at any point which might panic. If there is no defer then this is not necessary. This is implemented. We could also detect whether there is a recover in any of the defers. If not, we would need to mark only output params that the defer actually references (and the closure mechanism already does that). This is not implemented. Fixes #18860.
