[JSC][Temporal] Fix non-ISO calendar dayOfYear
https://bugs.webkit.org/show_bug.cgi?id=319305
Reviewed by Yijia Huang.
Temporal dayOfYear currently returns the ISO ordinal day for every calendar.
Read UCAL_DAY_OF_YEAR through CalendarICUBridge for non-ISO calendars and use
the existing proleptic Gregorian arithmetic path where required. This fixes
PlainDate, PlainDateTime, and ZonedDateTime for non-ISO calendars.
Test: JSTests/stress/temporal-non-iso-dayofyear.js
* JSTests/stress/temporal-non-iso-dayofyear.js:
Added coverage for non-ISO calendar dayOfYear values and Gregorian arithmetic
boundaries.
* Source/JavaScriptCore/runtime/TemporalPlainDatePrototype.cpp:
(JSC::temporalPlainDatePrototypeGetterDayOfYear):
* Source/JavaScriptCore/runtime/TemporalPlainDateTimePrototype.cpp:
(JSC::temporalPlainDateTimePrototypeGetterDayOfYear):
* Source/JavaScriptCore/runtime/TemporalZonedDateTimePrototype.cpp:
(JSC::temporalZonedDateTimePrototypeGetterDayOfYear):
Use CalendarICUBridge for non-ISO calendar dayOfYear values.
* Source/JavaScriptCore/runtime/temporal/core/CalendarICUBridge.cpp:
(JSC::TemporalCore::japaneseCalendarGregorianTransitionYear):
(JSC::TemporalCore::calendarDayOfYear):
Add the day-of-year bridge and name the Japanese Gregorian transition year.
* Source/JavaScriptCore/runtime/temporal/core/CalendarICUBridge.h:
(JSC::TemporalCore::calendarDayOfYear):
Declare the bridge.
