You would put them in syms_of_xdisp, and that's basically it.

  x = Qnil;
  staticpro (&x);
  y = Qnil;
  staticpro (&y);

It's probably a good idea to make sure the vars are initialized to
something before there is any chance that MPS sees them, or we actually,
when we trace them.

The calls to igc_..._var would also go there, also with inits.

Thanks!
