SDK-15294: Update SignatureEvaluator to handle Vector.<*>
* I re-enabled SignatureExtension failure warnings since ASC is in churn (if a soft-assertion (e.g. unexpected code path) fails, I assume that the signature is unsafe to use and revert to conservative (slow) invalidation behavior). Without these warnings on, you will not be aware of this, and therefore it will not get fixed. A bug has been filed to disable it for release.
QA: Yes, full signature suite, please. And we need tests for Vector.
