[15] RFR: 8241082: Upgrade IANA Language Subtag Registry data to 03-16-2020 version

[Roger Riggs]

Hi Naoto,

EquivMapsGenerator.java: 242
It looks odd to put the warning about being an auto-generated file in 
the middle of the declarations.
Perhaps add it to the headerText.

The existing maps are not pre-sized, is it important to pre-size the new 
ones.
There's no particular reason to pre-concatinate the new source lines.  
Separate writes would be fine too.

Roger
