Remove op_end
https://bugs.webkit.org/show_bug.cgi?id=306661
rdar://169310061
Reviewed by Yusuke Suzuki.
op_end is semantically the same as op_ret (but has worse codegen in
Baseline). Let's remove it and use op_ret everywhere instead.
Had to fix a few other places that were using op_end as a sentinel
opcode in peephole optimizing bytecode. I replaced it with op_debug
since that opcode shouldn't exist outside bytecode generated for
debugging.
No new tests, no new behavior. Covered by existing tests.
