Improve expected type determination for the following cases: - search back further through ast path to handle cases where the position's node is more than two nodes from the ancestor node with type information - generate expected type for return statements - wrap and unwrap pointerness from expected type when position is preceded by "*" (dereference) or "&" (reference) operators, respectively - fix some false positive expected types when completing the "Fun" (left) side of a CallExpr Change-Id: I907ee3e405bd8420031a7b03329de5df1c3493b9 GitHub-Last-Rev: 20a0ac9bf2b5350494c6738f5960676cc50fb454 GitHub-Pull-Request: golang/tools#93 Reviewed-on: https://go-review.googlesource.com/c/tools/+/174477 Run-TryBot: Rebecca Stambler <rstambler@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Rebecca Stambler <rstambler@golang.org>
