    arm: fix bootstrap issue with arm_noce_conversion_profitable_p patch [NFC]
    
    This obvious patch fixes two warnings introduced with the implementation of
    arm_noce_conversion_profitable_p hook.
    
    gcc/ChangeLog:
    
            * config/arm/arm.cc (arm_noce_oncersion_profitable_p): Remove unused
            argument name.
            (arm_is_v81m_cond_insn): Initialize variable.
    
    (cherry picked from commit 5fb1ab539e3315175d2e843f4ce40bde6dd7c520)
