Attached is a patch based off #26647 which converts ceval to read opcode/oparg by casting next_instr to an unsigned short. I don't believe we need to complicate the code with checking the pointer alignment of the instruction stream; some effort must be gone through to generate bytecode off alignment, & if the issue comes up it's because someone's using the C API on a CPU that doesn't support unaligned reads to generate their own custom bytecode. Anyways pybench went from 16.5 on wordcode to 16.0 for me

The change works through replacing NEXTOP/NEXTARG with a NEXTOPARG macro
