Right, JSMin makes a fair amount of assumptions about the code that it will

Well, usually it's easier to port code that you wrote yourself, so I went ahead
and made the attached patch. It seems, that even in php, its performance is
quite good, in most tested cases it was about the same speed or slightly faster
than JavascriptDistiller.

For now I removed $wgResourceLoaderMinifyJSVerticalSpace. As the new minifier
knows when semicolon insertion will be triggered, it can safely put everything
on a single line. For readability it may be considered to add a few newlines,
though, maybe before each "function"?

I left JavaScriptDistiller.php in place to ease comparing and testing. I also
added a few test cases in
tests/phpunit/includes/libs/JavaScriptMinifierTest.php, probably need a few
more, though.
