RFR: 8025067: (xs) Arrays.parallelPrefix may fail to throw NPE for null op

[Mike Duigou]

After posting the webrev I decided that an update to the regression test was going to be necessary. Here's the updated webrev including additional unit tests. Unfortunately I had to cut-and-paste some "library" code for exception checking. The "library" code will need to be cleaned up eventually.
