It's again the combiner:

26.life1:

(insn 21 19 22 2 (set (subreg:SI (reg:DI 64 [ D.654 ]) 0)
        (const_int 1 [0x1])) 34 {*movsi_1} (insn_list:REG_DEP_TRUE 73 (nil))
    (nil))

(insn 22 21 23 2 (set (strict_low_part (subreg:QI (reg:DI 64 [ D.654 ]) 4))
        (const_int 1 [0x1])) 46 {*movstrictqi_1} (insn_list:REG_DEP_TRUE 21
(nil))
    (nil))

27.combine

(note 21 19 22 2 NOTE_INSN_DELETED)

(insn 22 21 23 2 (set (reg:DI 64 [ D.654 ])
        (const_int 1 [0x1])) 56 {*movdi_2} (nil)
    (nil))
