Title: Test HHVM on Travis-CI, allowing failures.

This is untested, just making a PR to see what happens - sorry if it's a distraction.

Most HHVM failures are probably HHVMs fault, but I have some some cases where HHVM failures reveal incorrect code that just happens to work on Zend, so there may be some value to running these tests even with no intention of fixing all failures yet.
