merge revision(s) 63868,63870: [Backport #14897]

	Fix a bug of peephole optimization

	```
	  if   L1
	L0:
	  jump L2
	L1:
	  ...
	L2:
	```

	was wrongly optimized to:

	```
	  unless L2
	L0:
	L1:
	  ...
	L2:
	```

	To make it conservative, this optimization is now disabled when there is
	any label between `if` and `jump` instructions.
	Fixes [Bug #14897].

	compile.c: remove unreachable jump only

	* compile.c (iseq_peephole_optimize): remove unreachable jump
	  instruction only.  if it is labeled and referred from other
	  instructions, it is reachable and must not be removed.
