compiler: Handle newlines in general comments.
On comments, the specification says
(http://golang.org/ref/spec#Comments): General comments start with the
character sequence /* and continue through the character sequence */.
A general comment containing one or more newlines acts like a newline,
otherwise it acts like a space.
Fixes golang/go#11528.
