Unicode 15.1 added the following "simple" case-folding entries:
```
1FD3; S; 0390; # GREEK SMALL LETTER IOTA WITH DIALYTIKA AND OXIA
1FE3; S; 03B0; # GREEK SMALL LETTER UPSILON WITH DIALYTIKA AND OXIA
FB05; S; FB06; # LATIN SMALL LIGATURE LONG S T
```
The behavior of `/\p{RGI_Emoji}/v` and other properties of strings depends on the Unicode & Emoji version being used in the JavaScript engine. This patch adds tests verifying new additions to `RGI_Emoji` for each release of the Unicode Emoji standard are correctly matched.
While we're at it, use assert() instead of assert.sameValue() for brevity,
if we are not specifically testing that the return value of hasOwnProperty
is the value true or false; and add more informative assertion messages to
help with debugging.
In some cases, the Object.hasOwnProperty.call could be replaced with
verifyProperty(), if the property descriptor was also being verified at
the same time.
This fixes some tests that were faulty to begin with: a common mistake was
Object.hasOwnProperty(obj, prop) which is probably going to return false
when that's not what you want.
The only instances left of `Object.hasOwnProperty` are one regression test
in implementation-contributed which I can't tell if it was intentionally
needed to trigger the regression, and a few instances of
`Object.hasOwnProperty('prototype')` which would defeat the purpose to
convert into `Object.prototype.hasOwnProperty.call(Object, 'prototype')`
form.
Closes: #3524
Adds a test similar to the one in #3697, but in the main tree.
The six code points in this test have an "F" for full case mapping in
CaseFolding.txt, and so they should not be considered in the
Canonicalize operation.
Current versions of SpiderMonkey and V8 fail this test, others pass.
These tests should cover the full functionality of the .groups object (and
the .indices.groups object, in the case of the /d flag) for RegExp.p.exec
and String.p.match:
- Matched DNCG has a result
- Unmatched DNCG is present and undefined
- DNCG matched in previous iteration but not in current iteration is
treated as unmatched
- Iteration order of properties corresponds with source order
See: #3704
Each named capturing group should count as its own parenthesized capturing
group, even if it has the same name as another group. So, some of these
expectations were missing `undefined` array elements for the variant of
the `x` capturing group that didn't match.
In the other expectations, we forgot to take into account that the
backreference is not inside a capturing group, so the group match should
not have doubled letters in it.
Parse-time syntax for RegExp literals is already tested. These two files
test runtime RegExp compilation, with respect to duplicate named capture
groups.
See: #3704
For completeness, as we are doing in newer brand checking tests such as
those of Temporal, call these getters with a function object and a bigint
as the receiver.

This reverts commit b690cb67be, reversing
changes made to 50dd431dff. This is
necessary because the reverted changeset reduced coverage by an unknown
extent.
