Drop support for HHVM officially?

[ravage84]

We recently opted out of building the framework on HHVM in Travis CI due to issues with it and seemingly a lack of interest in it: 6339c68

On another note, both Symfony and doctrine will drop their support for HHVM:

What is our stance towards supporting HHVM for CakePHP 3.x, 2.x or in general?

I am 👍 on this. We haven't had passing tests on HHVM in 6+ months. I don't think we can say we 'support' it if our tests can't pass.

We never had 100% tests passing in hhvm. We tried, though

Given the features of PHP we use, HHVM didn't make it easy to get to 💯
