RFR(XS): 8246109: Remove unneeded undef CS

[Mikael Vidstedt]

Please review this small change which removes a now unneeded #undef:

JBS: https://bugs.openjdk.java.net/browse/JDK-8246109
webrev: http://cr.openjdk.java.net/~mikael/webrevs/8246109/webrev.00/open/webrev/


Background (from JBS):

In src/hotspot/share/prims/methodHandles.cpp one can find the following code: 

#undef CS // Solaris builds complain 

I chose not to remove it as part of the Solaris/SPARC removal (JDK-8241787) the the fear of breaking some other platform and making the already-challenging work even harder. 

I have now verified that removing the line at least works for all the Oracle builds.


Testing:

tier1 + builds-tier{2..5}

Cheers,
Mikael
