d6de2c03cb * generic part of r26050 from the hlcgllvm branch: made tcgvecnode hlcg-safe 
o in particular, add tdef size information to the update_reference*()
     methods, and factored out offset adjustments into its own method
   o also make sure the passed size to update_reference*() corresponds to the
     actual size of the index, as it's no longer guaranteed to be ptruint
     since the previous commit
