I noticed that current VarHandle/Unsafe test cases do not test the always-failing cases. Strong CASes do test both always-success and always-failing scenarios, while weak CASes only test spurious-failure tests. We should be also testing always-failing cases for these. Weak CAS can spuriously fail, but it cannot spuriously succeed.
The PR looks large, but the actual changes are in `*.template` files, and the rest is generated from them.
