Please review this fix in for wrong rounding-mode mode behavior of
NumberFormat.format(double) in HALF_UP case.
https://bugs.openjdk.java.net/browse/JDK-8039915

<http://cr.openjdk.java.net/%7Eolagneau/8039915/webrev.00>
Bug came from a mix of a '5' and 'greater than 5' last digit, when this
digit was the last one.
Fix consists in properly separating the two cases and cleanly test all
possible cases (see JDK-8039915 comments) for the HALF_UP rounding-mode.
TieRoundingTest test has been extended with a few cases to check such
cases (last digit at the rounding position and != '5')
testing: jtreg, jck8, jprt
Best regards,
Olivier Lagneau
