Just mechanical conversion to remove boilerplate code. When .tq and .h
files didn't agree on what a field is named, I used the name from the .h
file. In a couple of cases the generated accessor became slightly more
specific (HeapObject instead of Object), and I had to update the code
that uses those accessors accordingly.
