RFR: JDK-8134408: Disable warnings for jdk libraries triggered by SS12u4

[Erik Joelsson]

Hello,

Please review this small change, adding some new disabled warnings for 
the solstudio toolchain type. When compiling using SS12u4, some new 
warnings are triggered and for the short term, the easiest solution is 
to simply disable them. I have filed separate bugs for fixing the warnings.
