When files are copied into place, check whether opcode invalidation is available and attempt to invalidate to avoid unintended behavior or fatal errors from themes, plugins, or core.
Introduces `wp_opcache_invalidate()` to allow safe invalidation of PHP files from opcode cache, and a filter, `wp_opcache_invalidate_file` to override the behavior.
Replaces the existing calls to `opcache_invalidate()` in the plugin and theme editors to use the new function.
Thanks to jnylen0 for porting over a patch from ClassicPress that provided much of the approach for what is being committed.

In WordPress 3.2 support for IE6 was dropped, IE7 followed a few versions later. With the 4.8 release, WordPress officially ended support for Internet Explorer versions 8, 9, and 10. Yet, we still have shipped CSS for the unsupported IE versions....until now! Goodbye to ie.css and star hacks!
* Removes ie.css and `ie` style handle.
* Removes IE specific class names and any related CSS.
* Drops support for IE8 and older in `wp_customize_support_script()`.
* Updates compatibility mode for CSS minification to `ie11`.

This avoids the performance overhead of the function call every time `dirname( __FILE__ )` was used instead of `__DIR__`.
This commit also includes:
* Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls.
* Replacing `include` statements for several files with `require_once`, for consistency:
* `wp-admin/admin-header.php`
* `wp-admin/admin-footer.php`
* `wp-includes/version.php`

This allows update failures caused when the native PHP JSON extension is missing to be distinguished from updates that fail because the site does not meet the minimum PHP requirements.

The PHP native JSON extension has been bundled and compiled with PHP by default since version 5.2.0. Because the minimum version of PHP required by WordPress is now 5.6.20 (see #46594 and [45058]), the related polyfills and workarounds have been removed (see [46205-46206,46208]).
However, even though the JSON extension is now included in PHP by default, it is still possible to disable the extension in a custom configuration. This change will prevent sites from upgrading if the JSON extension is disabled to prevent compatibility issues.

We've extracted wp-includes/wp-a11y.js to a reusable package wordpress/a11y which is published on NPM. Let's make sure this package is also used in WordPress core. Once all the JavaScript is built using webpack, we can also import this package wherever it is used and configure webpack to load is an external.

* Add missing translator comments.
* Fix placement of some translator comments. Translator comments should be on the line directly above the line containing the translation function call for optimal compatibility with various `.pot` file generation tools. The CS auto-fixing, which changed some inconsistent function calls to multi-line function calls, is part of the reason why this was no longer the case for a select group of translator comments.
Includes minor code layout fixes.
Polyglots, rejoice! All WordPress core files now have translator comments for all strings with placeholders!

Noteable changes:
- The `magic_quotes_runtime` and `magic_quotes_sybase` settings were removed in PHP 5.4, so no longer need to be set.
- Some functions that use external libraries can generate errors that can't be tested for, so are globally allowed to silence errors.
- Quite a few functions would cause errors if `safe_mode` was set. This setting was removed in PHP 5.4.
- Only a handful of `header()` calls needed corresponding `headers_sent()` checks for unit tests to pass, but more may need to be added as the nightlies builds are tested.

JSHint inherits a license from JSLint that includes the clause "The Software shall be used for Good, not Evil." WordPress's license specifically allows grants the freedom to run the program, for any purpose. Please note, this is not an encouragement of evil. Rather than doing something evil, how about learning to love those around you. Instead of tweeting lies and saying people are "Not Good!", help your neighbor. In the words of Lin Manual Miranda, "Love is love is love is love is love is love is love is love, cannot be killed or swept aside."
This replaces JSHint with esprima, a part of the larger jQuery project, and a custom wrapper for some basic error checking within codemirror.
The existing JSHint configuration is kept in place in case someone wants to use that, but they can only do so for Good.
