IRA: Don't create new regs for debug insns (PR80429)

In split_live_ranges_for_shrink_wrap IRA also splits regs that are
only used in debug insns, leading to -fcompare-debug failures.

PR rtl-optimization/80429
* ira.c (split_live_ranges_for_shrink_wrap): Don't split regs that
are only used in debug insns.
