For example, given
`[[File:Foobar.jpg|alt=&]]`
PHP will render this in HTML as alt="&" while HHVM correctly renders alt="&".
This is a bug in the tokenizer, where we take a shortcut in Tokenizer::handleCharRefs() and then turn around and decode the entities again "the long way", leading to a double-decode.

[mediawiki/libs/RemexHtml@master] Don't double-decode HTML entities on non-HHVM PHP
The patch is merged, but we're going to need a new version of remex released to composer and mediawiki-core updated to require the new version before this bug is actually fixed in production uses of php 7 (ie, when running the php 7 jenkins tests).
