Log:
compiler: Consider multi-result calls in escape analysis.

When building connection graphs between objects, the analysis
only handled calls of the form `call(...)` or `var := call(...)`.
Functions with multiple results being used e.g. `var, _ = call(...)`
were not analyzed, causing some escaping variables to be marked as
non-escaping.
