merge revision(s) 61617,61618: [Backport #14273]
compile.c: remove more unreachable chunk
* compile.c (remove_unreachable_chunk): remove beyond labels to be
removed.
compile.c: fix stack consistency error
* compile.c (iseq_peephole_optimize): fix stack consistency error

with `leave`, which is never reached but needed to adjust sp
calculation. [ruby-core:84589] [Bug #14273]
