RFR 8015790 Remove duplicate spliterator tests

[Paul Sandoz]

Hi,

This RFR proposes to remove some duplicate spliterator tests.

The tests: 

http://hg.openjdk.java.net/jdk8/tl/jdk/file/tip/test/java/util/stream/test/org/openjdk/tests/java/util/stream/SpliteratorTraversingAndSplittingTest.java
http://hg.openjdk.java.net/jdk8/tl/jdk/file/tip/test/java/util/stream/test/org/openjdk/tests/java/util/stream/SpliteratorLateBindingFailFastTest.java

are duplicates of: 

http://hg.openjdk.java.net/jdk8/tl/jdk/file/tip/test/java/util/Spliterator/SpliteratorTraversingAndSplittingTest.java
http://hg.openjdk.java.net/jdk8/tl/jdk/file/tip/test/java/util/Spliterator/SpliteratorLateBindingFailFastTest.java

and the former should be removed.

Paul.
