JDK 9 RFR of JDK-8167525: update jdk tests to remove @compile --add-modules workaround

[Amy Lu]

Please review the patch to remove the @compile --add-modules workaround.

In the past, tests added --add-modules to @compile (JDK-8169231) or to 
@run (JDK-8156579) to workaround jtreg issue CODETOOLS-7901761. 
CODETOOLS-7901761 has been fixed in 4.2/b05, workaround in tests should 
be reverted.

bug: https://bugs.openjdk.java.net/browse/JDK-8167525
webrev: http://cr.openjdk.java.net/~amlu/8167525/webrev.00/

Note that sun/nio/cs/OLD/TestIBMDB.java was added to ProblemList.txt in 
JDK-8169231, indicate this (JDK-8167525) as related bug. But now this 
test pass, so removed it from ProblemList.txt

Thanks,
Amy
