From-SVN: r222599

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.

From-SVN: r222598

If a closure escapes, the enclosed variables must escape via the
closure.  Reachability analysis had a bug where the enclosed
variables were not considered as reachable from the closure.
