RFR: 8318682: SA decoding of scalar replaced objects is broken [v7]

[Tom Rodriguez]

> The changes for JDK-8287061 didn't update the SA decoding logic and there are other places where the decoding has gotten out of sync with HotSpot.  Some of them can't be tested because they are part of JVMCI but I've added a directed test for the JDK-8287061 code and a more brute force test that tries to decode everything.
