Check for redundant if err != nil constructs. (#319)

* Check for redundant if err != nil constructs.

Detect and complain about constructs like:

if err := foo(); err != nil {
  return err
}
return nil

(Issue https://github.com/golang/lint/issues/312)

* Rewrite lintIfError without using matchers.

Also don't emit lint errors if there are any comments explaining the
construct (between if and return statements).
