there is a new method in the TCK, please consider implementing it - e.g. use 
the provided builder instead of creating your own.

The change is result of
https://github.com/graalvm/truffle/pull/146
and it opens up new possibilities in the test compatibility kit testing. For 
example I have long open request to test importSymbol method. Or we'd like to 
test debugging capabilities of languages [like we do for SL]
(https://github.com/graalvm/truffle/blob/a4d9f095b6e2d2eb370aff6d848055adeac627a5/truffle/com.oracle.truffle.sl.test/src/com/oracle/truffle/sl/test/SLDebugTest.java) 

With the new method signature these tasks should be easier than ever.
