I wouldn't think so.  This cpu setup should be happening very early.

We could perhaps look at arranging fields such that all the fields that are 
"shared" between the contexts are up front, and use the qemu standard

  memcpy(new, old, offsetof(TCGContext, end_common_fields));

trick, and zero the rest.
