Clemens Hammacher a3baa35372 [simulator] Make Call variadic
In order to remove the CALL_GENERATED_CODE macro, it helps a lot to
unify the interfaces of the simulators and make the Call method variadic
in the number of arguments.
This CL does that for each simulator. A follow-up CL will then
completely remove the CALL_GENERATED_CODE macro and replace uses with
the (new) GeneratedCode wrapper.
