Test wanted: CREATE properly clears dirty return data

[chfast]

Scenario:

1. At depth 0 we execute CREATE or CREATE2 instruction.
2. Inside the "create" we invoke somethings what produces non-empty return data. Can be a call to other contract, reverting create, call to a precompile. After this the RETURNDATASIZE != 0.
3. Initial "create" finishes successfully.
4. After "create" check if correctly RETURNDATASIZE == 0.

This is tested for CREATE but only the case when a precompile is called. None of this is tested for CREATE2.

These are state test failures for broken CREATE / CREATE2 implementations:
