The BSON tests in tests/bson/*phpt test both working and failure (wrong param count eg.) cases. Please split them up so that we can test for the working stuff, and so that I can ignore the exception and param parsing errors when running through HHVM (as it does it different).

These test cases are affected (maybe more):

tests/bson/bson-binary-001.phpt
tests/bson/bson-javascript-001.phpt
tests/bson/bson-regex-001.phpt
bson/bson-timestamp-001.phpt
tests/bson/bson-utcdatetime-001.phpt
