[PHIEliminate] Move dbg values after phi and label
If there are DBG_VALUEs between phi and label (after phi and before label),
DBG_VALUE will block PHI lowering after the LABEL. Moving all DBG_VALUEs
after Labels in the function ScheduleDAGSDNodes::EmitSchedule to avoid
impacting PHI lowering.
before:
PHI
DBG_VALUE
LABEL
after: (move DBG_VALUE after label)
PHI
LABEL
DBG_VALUE
then: (phi lowering after label)
LABEL
COPY
DBG_VALUE
