Without debug insns, REG_N_CALLS_CROSSED was zero for that pseudo, so
sched_analyze_reg added a dep between the pseudo setter and an earlier
(lib)call.

The testcase has a debug insn referencing a pseudo right before an
insn that modifies the pseudo.
Without debug insns, REG_N_CALLS_CROSSED was zero for that pseudo, so
sched_analyze_reg added a dep between the pseudo setter and an earlier
(lib)call.
With debug insns, we miscomputed REG_N_CALLS_CR
