In Chromium tree, ICU is rolled to 63.1. And, auto-roller will soon
try to roll ICU in v8 to 63.1. Due to a nodejs trybot issue,
autoroll needs a manual intervention. In the meantime, this CL
will get rid of other blocking issues for ICU update.
Prepare for the ICU roll by revising test/intl as following:
* Line breaking loose mode is now supported in the
Chromium's copy of ICU. Adjust the test expectation.
* ICU's uloc_* can handle overlong locale ids. Drop tests
that are not valid any more.
Once ICU is rolled, a couple of TSAN-suppressed tests can
be unsuppressed, but that has to be done in a separate CL.

- Get rid of an unnecessary call to uloc_canonicalize in js-locale.
- Do not use regex, but rely on ICU for the structrural validity check
with Chrome's ICU or ICU 63 or newer. Otherwise, continue to use regex.
This became possible thanks to a couple of bug fixes in ICU ToT that
were cherry-picked for Chromium's ICU.
Not yet done is to change js-locale to use CanonicalizeLocale().
That will make a few more tests pass.

Not all 2 or 3 letter language codes are canonical. Some of them need
to be canonicalized.
Specifically, exclude {jw,ji,iw,in} and all three-letter codes from the
fast path except for 'fil'.
{jw,ji,iw,in} are deprecated ISO 639 codes for
{Javanese, Yiddish, Hebrew, Indonesian}. They should be
canonicalized to {jv,yi,he,id}. So, do not return early
in the fast path, but pass it down to the full canonicalization.
In addition, there are 70+ deprecated 3-letter codes that need to be
replaced by their modern equivalents. Instead of checking and replacing
in v8, just pass them to ICU to handle.
Along with the following ICU change, two more tests will pass.
https://chromium-review.googlesource.com/c/chromium/deps/icu/+/1026797
These two tests still fail because of the disagreement between ICU and the test
expectations about 5 grandfathered tags with no preferred value (e.g.
i-default, zh-min, cel-gaulish).

ECMA 402 v2 made Intl constructors more strict in terms of how they would
initialize objects, refusing to initialize objects which have already
been constructed. However, when Chrome tried to ship these semantics,
we ran into web compatibility issues.
This patch tries to square the circle and implement the simpler v2 object
semantics while including a compatibility workaround to allow objects to
sort of be initialized later, storing the real underlying Intl object
in a symbol-named property.
The new semantics are described in this PR against the ECMA 402 spec:

So, there's no need to use a slow transliteration API for uppercasing

When I18N is enabled, use ICU's case conversion API and transliteration
API [1] to implement String.prototype.to{Upper,Lower}Case and
String.prototype.toLocale{Upper,Lower}Case.
* ICU-based case conversion was implemented in runtime-i18n.cc/i18n.js
* The above 4 functions are overridden with those in i18n.js when
--icu_case_mapping flag is turned on. To control the override by the flag,
they're overriden in icu-case-mapping.js
Previously, toLocale{U,L}Case just called to{U,L}Case so that they didn't
support locale-sensitive case conversion for Turkic languages (az, tr),
Greek (el) and Lithuanian (lt).
Before ICU APIs for the most general case are called, a fast-path for Latin-1
is tried. It's taken from Blink and adopted as necessary. This fast path
is always tried for to{U,L}Case. For toLocale{U,L}Case, it's only taken
when a locale (explicitly specified or default) is not in {az, el, lt, tr}.
With these changes, a build with --icu_case_mapping=true passes a bunch
of tests in test262/intl402/Strings/* and intl/* that failed before.
Handling of pure ASCII strings (aligned at word boundary) are not as fast
as Unibrow's implementation that uses word-by-word case conversion. OTOH,
Latin-1 input handling is faster than Unibrow. General Unicode input
handling is slower but more accurate.
See https://docs.google.com/spreadsheets/d/1KJCJxKc1FxFXjwmYqABS0_2cNdPetvnd8gY8_HGSbrg/edit?usp=sharing for the benchmark.
This CL started with http://crrev.com/1544023002#ps200001 by littledan@,
but has changed significantly since.
