RFR: 8024014 & 8024015 : (xs) TEST.groups updates

[Mike Duigou]

Hello all;

This is a review for two changesets. The first change (JDK-8024014) splits up the jdk_util test group a bit by introducing three sub-groups, jdk_collections, jdk_stream and jdk_concurrent. The main advantage is that it's easier/quicker to test individual components. The intent is that the test groups are aligned with bug database sub-components.

The second change moves some important lambda related tests from languishing in obscurity in the jdk_other group to the jdk_lang group to reflect their importance and relation to other tests. These tests are contained in the jdk/lambda directory.

The combined webrev is here:

The effect of these changes won't be visible to most people until JDK-8015068 is integrated.

Thanks,

Mike
