[JSC][Temporal] Give CalendarMonthDayToISOReferenceDate and
NonISOMonthDayToISOReferenceDate their own functions
https://bugs.webkit.org/show_bug.cgi?id=321661
rdar://184788558
Reviewed by Yusuke Suzuki.
monthDayFromFields was one function with hand-written ISO and non-ISO branches,
each re-deriving the
month/day clamp and reference-year logic independently. Split it so each spec
AO has its own
function (ecmaReferenceYearWithRegularFallback,
nonISOMonthDayToISOReferenceDate,
monthDayToISOReferenceDate), delegating to nonISOCalendarDateToISO instead of
re-deriving its logic
by hand, and drops the ISO path's now-unnecessary leap/non-leap proxy-year
substitution.
Also unifies isoToCalendarFields's roc/buddhist/japanese handling so japanese
stops opening ICU only
to discard every field it reads, and gives nonISOCalendarDateToISO an
effectiveMonth fallback for
its one caller that now supplies a monthCode with no ordinal.
No intended behavior change.
