compiler: mark Call_expression multiple results as a result struct

In https://go.dev/cl/343873 we stopped padding zero-sized trailing
fields in functions that return multiple results where the last result
is zero-sized. This CL makes the corresponding change on the caller side.

The test case is https://go.dev/cl/479898.

Fixes golang/go#55242
