[1.8] Reduce allocations

[Oondanomala]

Should be faster (I hope).
Before it was one of the biggest BlockPos allocators, now it's completely gone.

Probably applies to all other versions, I don't know how BlockPos works there though.
(it should matter less on modern Java which has an incremental garbage collector)
