Currently, to ensure OAS2FUNC results are assigned in the correct order, they're always assigned to temporary variables. However, these temporary variables are typed based on the destination type, which may require an interface conversion. This means walk may have to then introduce a second set of temporaries to ensure result parameters are all copied out of the results area, before it emits calls to runtime conversion functions. That's just silly. Instead, this CL changes order to allocate the result temporaries with the same type as the function returns in the first place, and then assign them one at a time to their destinations, with conversions as needed. While here, also fix an order-of-evaluation issue with has-ok assignments that I almost added to multi-value function call assignments, and add tests for each.
