      Fix two DCHECK failures in ICU case mapping code · ac9e6285
      jshin authored 
      1.
DCHECK in runtime-i18n.cc for case mapping was wrong to
assume that the longest primary language tag is 3 characters.
BCP 47 actually allows up to 8 characters.

2. GetFlatContent() was called to a string without flattening it first.

      [intl] Remove redundant type checking system · 788c96a9
      littledan authored 
      Previously, the Intl implementation tracked types two ways:
 - In the intl_initialized_marker_symbol
 - In various named properties of the intl_impl_object_symbol value

As far as I can tell, these will never disagree with each other,
modulo bugs in Intl itself. This patch removes the second type
checking system.

This reland includes a fixed type check for
Intl.DateTimeFormat.prototype.formatToParts , which is the only Intl
method which is not bound. All future methods will follow this
pattern.

The second reland ensures that a newly inserted test is only run
if Intl is present.

      [intl] Add new semantics + compat fallback to Intl constructor · b0a09d78
      littledan authored 
      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:
https://github.com/tc39/ecma402/pull/84

      Fix the uppercasing of U+00E7(ç) and U+00F7(÷) · 2f5da9a5
      jshin authored 
      Due to a typo in runtime-i18n.js, 'ç'(U+00E7) was not uppercased while
'÷'(U+00F7) was incorrectly uppercased to '×'(U+00D7).

Add a comprehensive test for Latin-1 supplemental block (U+00A0 ~ U+00FF).
(they're special-cased for speed-up and needs to have a test for the range.).

      Use a regular ICU API for el-Upper · 4f224b39
      jshin authored 
      ICU now supports uppercasing in Greek via its regular uppercasing API.
So, there's no need to use a slow transliteration API for uppercasing
in Greek.

This CL includes rolling ICU to ICU 58.1.

Besides, drop intl402/Intl/getCanonicalLocales/weird-cases from
test262.status because it passes now with ICU 58.1.

      Avoid calling the builtin String.prototype.split in Intl · 97e8046e
      littledan authored 
      The Intl code previously called the initial value of String.prototype.split
for some internal operations. However, this did not have the intended effect
as Intl only needs to split strings by strings, but String.prototype.split
has integration with Symbol.split for RegExps.

This patch replaces the calls of StringSplit in the Intl implementation
with direct calls to the %StringSplit runtime function to avoid the issue.

      Use ICU case conversion/transliterator for case conversion · b348d47b
      jshin authored 
      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.
