* reload.c (find_reloads): Generate REG_LABEL_OPERAND, not
REG_LABEL when replacing an operand with a LABEL_REF for a

(delete_related_insns): Handle both REG_LABEL_TARGET and
REG_LABEL_OPERAND notes. For JUMP_P insns with labels with zero
reference count, delete and fallthrough. Move finding-next-
non-deleted insn last in the function. Look at all INSN_P insns
for REG_LABEL_OPERAND notes.

JUMP_LABEL, output the INSN_UID of it.

usage count increment; handle all INSN_P trial insns.
