[8u] RFR: [JDK 8u] JapanEraNameCompatTest fails

[Severin Gehwolf]

Hi,

Could somebody please review this fix for the failing
JapanEraNameCompatTest.java test (part of tier1)? The reason why it's
failing is that there are missing locale data for no and sr_Latn which
are exercised by the test. The original backport of JDK-8219781 didn't
include those as the changed sections in the JDK 11 patch didn't exist
in 8u. Those extra sections got introduced with JDK-8008577 or JDK-
8145136.

This patch adds locale data for locales left out in the JDK-8219781 8u
backport, except for JavaTimeSupplementary_in.java. That file doesn't
exist at all in 8u, hence I've left that out.

Missing locale info has been retrieved from JDK-8008577 and JDK-8145136 
both of which aren't suitable to get backported to 8u.

Bug: https://bugs.openjdk.java.net/browse/JDK-8244843
webrev: http://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8244843/01/webrev/

Testing: tier1. One less test failure, namely JapanEraNameCompatTest,
no longer fails.

Thoughts?

Thanks,
Severin
