Frank Tang a1e6efd80c [intl] Fix consistency in Intl API 
Fix several edge cases consistency issues with ICU discovered by test262 test by
using Intl Enumeration API
1. Work around ICU short coming of always fallback in currency display
 name so when the fallback is "none" in DisplayNames, the force fallback
code will produce the correct undefined from the of(currency_code) method.
2. Always check numbering system is not algorithm based numbering system
to fix DateTimeFormat/RelativeTimeFormat/NumberFormat
resolvedOptions().numberingSystem when the reqested numberingSystem is one
of the numbering systems that we filter out the resources and not supported.
3. Generalize the iso8601 bit solution in DateTimeFormat and rename it to
alt_calendar bit to also fix DateTimeFormat resolvedOptions report
calendar as "islamic" while requesting "islamic-rgsa".
4. Work around reporting inconsistency of currency code and display name
in ICU.

README 

This directory contains code for binding the test262 test suite
into the v8 test harness. The tests are checked out as a dependency from

  https://chromium.googlesource.com/external/github.com/tc39/test262

at a revision specified in the DEPS file as 'data' in this directory. They are
fetched with 'gclient sync'. To update to a newer version, please change the
DEPS file.

Using a newer version, e.g. 'deadbeef' may be possible but the tests are only
known to pass (and indeed run) with the DEPS revision. Example:

  cd data
  git fetch
  git checkout deadbeef

If you do update to a newer revision you may have to change the test
harness adapter code since it uses internal functionality from the
harness that comes bundled with the tests.  You will most likely also
have to update the test expectation file.
