This constructor creates a new QuickHashIntSet. The size is the amount of
bucket lists to create. The more lists there are, the less collisions you
will have. Options are also supported.

The amount of bucket lists to configure. The number you pass in will be
automatically rounded up to the next power of two. It is also

The options that you can pass in are: QuickHashIntSet::CHECK_FOR_DUPES,
which makes sure no duplicate entries are added to the set;
QuickHashIntSet::DO_NOT_USE_ZEND_ALLOC to not use PHP's internal memory
manager as well as one of QuickHashIntSet::HASHER_NO_HASH,
QuickHashIntSet::HASHER_JENKINS1 or QuickHashIntSet::HASHER_JENKINS2.
These last three configure which hashing algorithm to use. All options
can be combined using bitmasks.
