Reduced testcase to be attached. This is selective scheduling removing a
BARRIER and a JUMP:
(note 40 41 4 6 [bb 6] NOTE_INSN_BASIC_BLOCK)
(insn 4 40 54 6 (set (reg/v:SI 65 [ result ])
(const_int 1024 [0x400])) t.c:12 64 {*movsi_internal}
(nil))
(jump_insn 54 4 55 6 (set (pc)
(label_ref 21)) t.c:12 -1
(expr_list:REG_CROSSING_JUMP (nil)
(nil))
-> 21)
(barrier 55 54 21)
(code_label 21 55 22 7 2 "" [2 uses])
(note 22 21 52 7 [bb 7] NOTE_INSN_BASIC_BLOCK)
They cannot be removed since the edge is EDGE_CROSSING.
