/*
* The first field of every node is NodeTag. Each node created (with makeNode)
* will have one of the following tags as the value of its first field.
*
* Note that the numbers of the node tags are not contiguous. We left holes
* here so that we can add more tags without changing the existing enum's.
* (Since node tag numbers never exist outside backend memory, there's no
* real harm in renumbering, it just costs a full rebuild ...)
