        simplify-rtx: Simplify subregs of logic ops

    combine generates

    (set (zero_extract:SI (reg/v:SI 101 [ a ])
            (const_int 8 [0x8])

                (const_int 8 [0x8])
                (const_int 8 [0x8]))))

    instead of

    (set (zero_extract:SI (reg/v:SI 101 [ a ])
            (const_int 8 [0x8])
            (const_int 8 [0x8]))
        (subreg:SI (not:QI (subreg:QI (sign_extract:SI (reg:SI 107 [ b ])
                        (const_int 8 [0x8])
                        (const_int 8 [0x8])) 0)) 0))

    Update *one_cmplqi_ext<mode>_1 to support the new pattern.
