Tests generator and generated tests for Java 

As of commit, the generator produces tests for Java, Python 2 and 3,
NodeJS and Safari.
It’s a great relief to seethe full set of runtime tests pas identically
on all targets
The previous tests are now located at org.antlr.v4.test.tool, the files
have been cleaned up to remove duplicates
