7152866: Tests not run because they are missing the @run tag

[Alan Bateman]

I was looking at a test and happen to notice that it had a @build tag 
but no @run tag so the test wasn't actually running as expected (it 
wasn't a compile-only test). This prompted me to do a quick audit and I 
found several other tests with similar issues. The following webrev 
fixes the test description of several of these tests:

Note that I didn't fix all the tests. It turns out that some of these 
tests don't compile or or fail on one or more platforms. I've created 
bugs for these [1]. TestX11CS.java is one case where it's not worth 
trying to fix it to compile so I propose to delete it.

I've used the opportunity to remove some tests from the ProblemList 
while I was there.

Thanks,
Alan.
