This won't work with intrinsics because, while we've created the table of
variable names, we haven't filled it out by printing the variables. Maybe
the thing to do would be to make print_var use the variable's nominal name
if the print state is NULL and then just call print_instr(instr, NULL, 0,
fp) here.
Otherwise, I really want this.
