// Regression: pop and resize aborted on every call in a stage4 build.
//
// The emitters called runtime.slicePanic with the condition as an argument and
// no branch around it, but the runtime panic entries are unconditional: they
// panic the moment they are entered. So pop() on a non-empty slice and
// resize() within capacity both aborted, while legacy - which branches to a
// fault block - was correct. They now call runtime.sliceCheckPop and
// runtime.sliceCheckResize, entries that carry the test themselves.
