runtime/pprof: Undefined type referred to in function comment

[fawick]

What version of Go are you using (go version)?

1.9beta

What did you do?

Read documentation of runtime/pprof for Profiler Labels (http://tip.golang.org/pkg/runtime/pprof/#Labels)

What did you expect to see?

The function comment for http://tip.golang.org/pkg/runtime/pprof/#Labels
should describe the return value as type LabelSet.

What did you see instead?

The typename returned by http://tip.golang.org/pkg/runtime/pprof/#Labels
is LabelSet, but the documentation string refers to it as LabelList.
