In doing so, this caught an erroneous ToObject invocation. In the one
spot that requires the value to be an object (the invocation to
LengthOfArrayLike), we know by then the value is an object because all
other possibilities have been handled.
In doing so, this fixes a few minor issues:
1. We were accessing the "unicode" and "lastIndex" properties out of
order. This is somewhat frequently tested by test262, but not in
this case.
2. We were doing a Value::to_object() followed by Object::get(), rather
than just Value::get() as the spec dictates.
3. We were TRYing a step (CreateDataPropertyOrThrow) that should never
fail, and should have been a MUST.
RegExpExec already returns a ThrowCompletionOr so this potentional error
should be a completion. RegExp.prototype [ @@replace ] is tripped up by
this mistake when implemented closer to the spec.
Not much of a difference as TimeFraction just parses Fraction, but let's
do it correctly. Small mistake I did in 4b7f716.
Thanks to YouTube user gla3dr for noticing this :^)
There are 443 number system objects generated, each of which held an
array of number system symbols. Of those 443 arrays, only 39 are unique.
To uniquely store these, this change moves the generated NumericSymbol
enumeration to the public LibUnicode/NumberFormat.h header with a pre-
defined set of symbols that we need. This is to ensure the generated,
unique arrays are created in a known order with known symbols. While it
is unfortunate to no longer discover these symbols at generation time,
it does allow us to ignore unwanted symbols and perform less string-to-
enumeration conversions at lookup time.
This was not happening locally for me, neither when building Lagom on
Linux nor with the SerenityOS toolchain...

Being really close to Object.prototype.valueOf() name wise makes this
unnecessarily confusing - while it sometimes serves as the
implementation of a valueOf() function, it's an abstraction which the
spec doesn't have.
Use the appropriate getters to retrieve specific internal slots instead,
most commonly [[FooData]] from the primitive wrapper objects.
For the Object class specifically, use the Value(Object*) ctor instead.
For the test cases changed here, we now recognize "morning2" and
"afternoon2" from the CLDR, so the expected results now match the specs
and other engines.
In the CLDR, there aren't "night" values, there are "night1" & "night2"
values. This is for locales which use a different name for nighttime
depending on the hour. For example, the ja locale uses "夜" between the
hours of 19:00 and 23:00, and "夜中" between the hours of 23:00 and
04:00. Our CLDR parser is currently ignoring "night2", so this rename
is to prepare for that.
We could probably come up with better names, but in the end, the API in
LibUnicode will be such that outside callers won't even see Night1, etc.
In a future commit, the "part" view returned from FormatDateTimePattern
may be a view into a string that goes out of scope. Ensure the AO only
returns valid views. A similar approach is used in Intl.NumberFormat.
There are a few FIXMEs that will need to be addressed, but this
implements most of the prototype method. The FIXMEs are mostly related
to range formatting, which has been entirely ignored so far. But other
than that, the following will need to be addressed:
* Determining flexible day periods must be made locale-aware.
* DST will need to be determined and acted upon.
* Time zones other than UTC and calendars other than Gregorian are
ignored.
* Some of our results differ from other engines as they have some
format patterns we do not. For example, they seem to have a lonely
{dayPeriod} pattern, whereas our closest pattern is
"{hour} {dayPeriod}".
Unlike the locale, the data locale has Unicode locale extensions removed
(e.g. the data locale for "en-US-u-ca-gregory" is just "en-US"). Cache
the data locale for LibUnicode lookups during formatting.
