after the DIE creation, we construct the context first.
This touches creation of namespaces and global variables. The purpose is to
handle all DIE creations similarly: constructs the context first, then creates
the DIE and immediately adds the DIE to its parent.
We use createAndAddDIE to wrap around "new DIE(".
