Clemens Hammacher 30fabc4cdf Replace CALL_GENERATED_CODE by GeneratedCode wrapper 
This ensures that there is only one entrance point from C++ to
generated code, hence only one method has to be excluded from CFI.
It also introduces type safety by only allowing the code to be called
with the right arguments.
This CL includes minor drive-by fixes in the tests, like removing
unused dummy variables.
