Allow larger thread poly data

The poly data currently has the restriction of being less than a
pointer's size, but there is much more space in the `Thread.user_args`
array which can be utilized, this commit allows you to pass types that are
larger than pointer length as long as the total size of the poly data is
less than that of the `Thread.user_args`.
