RFR: 8214571: -Xdoclint of array serialField gives "error: array type not allowed here"

[Hannes Wallnöfer]

Please review:

Bug: https://bugs.openjdk.java.net/browse/JDK-8214571
Webrev: http://cr.openjdk.java.net/~hannesw/8214571/webrev.00/

I changed the handling of array types in reference tags from causing an error to just generating a link to the element type.

I only updated the existing tests, should I add a test specifically for @serialField as well?

Thanks,
Hannes
