Upgrade ICU to 54.1
ICU 54.1 comes with CLDR 26 locale data along with Lao and Khmer dictionaries
for line/word breaking, new interval/duration formatting support, display
context support for date-time and lang/region display name and many more.
To better support regional variants such as en-{CA,AU}, fr-CA, es-*, and de-CH,
the locale data for those variants are included.
The ICU data file (icudtl.dat) for non-Android platform is
256,960 bytes smaller than before.
On Android, it's 232,240 bytes larger because the currency display
name data was added for EcmaScript I18N API.
On Linux/Mac/Android/iOS, base::TestSuites initializer now sets the
ICU locale explicitly to en_US if the default locale is a POSIX locale
that is not supported because I got rid of word_POSIX to save about
100kB. Moreover, virtually none of our users uses a POSIX locale so that
testing on POSIX locale is not realistic.
en_GB time formatting changed in ICU 54.1/CLDR 26 and the expected results
are updated.
Noto to Sheriff: The above data size changes (reduction or increase) may
require the expected size adjustment.
