On the first `foreach` loop in Text_Diff::_check()`, `$prevtype` is `null`. As `instanceof` requires the class name term to be an object or string, a fatal error is thrown:
>Fatal error: Uncaught Error: Class name must be a valid object or a string on line 279
This change:
* Adds a simple test for the `Text_Diff::_check()` method, which is how the bug was discovered as the test could never pass with the code as-is.
* Adds a defensive guard to protect against the fatal. It checks if `$prevtype` is not `null` as a pre-condition to for checking the instance. This bugfix also resolves the failing test.

Dynamic (non-explicitly declared) properties are deprecated as of PHP 8.2 and are expected to become a fatal error in PHP 9.0.
There are a number of ways to mitigate this:
* If it is an accidental typo for a declared property: fix the typo.
* For known properties: declare them on the class.
* For unknown properties: add the magic `__get()`, `__set()`, et al. methods to the class or let the class extend `stdClass` which has highly optimized versions of these magic methods built in.
* For unknown ''use'' of dynamic properties, the `#[AllowDynamicProperties]` attribute can be added to the class. The attribute will automatically be inherited by child classes.
In this case, the properties, as used in the class methods, fall in the “known property” category.

This changeset replaces contracted verb forms like `doesn't`, `can't`, or `isn't` with non-contracted forms like `does not`, `cannot`, or `is not`, for better consistency across the WordPress administration. It also updates some corresponding unit tests strings.

- Add `phpcs:ignore` statements to compatibility checks in PHPMailer.
- Remove quotes around the assertion in an `assert()` call. This will trigger a deprecated notice under certain conditions on PHP 7.2.

PHP7 is deprecating PHP4 style constructors, so we need to modify our code to have _construct methods that fire before the named PHP4 style constructors. The PHP4 style constructors will call the PHP5 style constructor in case it is being called directly (usually via parent::METHOD).
This modifies external libraries to add PHP5 style constructors, but doesn't add a notice for when they are used. In WordPress core code, PHP4 style constructors are being given a call to _deprecated_constructor. To the PHP4 style constructor I say "I know that I can't take no more | It ain't no lie | I wanna see you out that door | Baby, bye, bye, bye..."
