some sort of activation object. Unify them in one pointer in
the ExecutionContext class, and unify it's handling where it's
actually the same.

Differences:
- push parameters on the stack, including space for CallData members
- call instructions calculate the argument start
- use temp space above the calldata to evaluate arguments
- fewer temporaries are needed when a call is done while generating the
arguments of another call
- when calling the function, the js stack space above the callData is
not used, allowing for optimizations in the future
- Array and ObjectLiteral use the same mechanism
