Allow (cv) void and incomplete arrays to be passed to the type traits.

Fixes PR8110, and thus PR8109, PR8097, and parts of PR8101, PR8105 and PR8107. Only a few traits have tests for incomplete arrays, since I'm not yet clear what the result for them should be; Howards wants to file a DR to change the standard.
