CL 35562 substituted zerobase for the pointer for interfaces containing zero-sized values. However, it failed to evaluate the zero-sized value expression for side-effects. Fix that. The other similar interface value optimizations are not affected, because they all actually use the value one way or another. Fixes #19246 Change-Id: I1168a99561477c63c29751d5cd04cf81b5ea509d Reviewed-on: https://go-review.googlesource.com/37395 Run-TryBot: Josh Bleecher Snyder <josharian@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: David Chase <drchase@google.com> Reviewed-by: Cherry Zhang <cherryyz@google.com>
