    arm: Remove spurious 'volatile' qualifier
    
    Remove the 'volatile' qualifier which looks like an oversight and is
    causing build errors:
    '++' expression of 'volatile'-qualified type is deprecated.
    
    gcc/ChangeLog:
    
            * config/arm/arm-builtins.cc (arm_init_mve_builtins): Remove
            volatile qualifier.
