Description: The code generator used PEEK(i) to read the i-th stack item (1-based). Since this just obscures the meaning, we're just emitting stack_pointer[-i] now. Similar for POKE(i, x), which becomes stack_pointer[-i] = x. Similar for JUMPBY(i), becomes next_instr += i. Also expand NEXTOPARG() -- in the expansion I found that it is redundantly extracting the opcode (in the case of a super-instruction) so removed that,leaving only oparg = (next_instr++)->op.arg. Issue: gh-102305
