My CROSSING_JUMP_P patch didn't handle insns that were copied by
emit_copy_of_insn_after, which previously would copy REG_CROSSING_JUMP
notes by virtue of them being != REG_LABEL_OPERAND.

This patch adds the missing copy.  Tested with profiledbootstrap on
x86_64-linux-gnu.  Committed as obvious.

Thanks,
Richard
