  For a peephole2 condition variable insn points to the first matched
insn.  In order to refer to the second matched insn use
peep2_next_insn(1) instead.

Bootstrapped and regtested on IBM Z.  Ok for mainline and gcc-{11,10,9}?

gcc/ChangeLog:

	* config/s390/s390.md (define_peephole2): Variable insn points
	to the first matched insn.  Use peep2_next_insn(1) to refer to
	the second matched insn.
