    arm: Convert vcmp[eq|ne]* in arm_mve.h to use only 's' builtin version
    
    There is no need to have a signed and an unsigned version of these
    builtins. This is similar to what we do for Neon in arm_neon.h.
    This mechanical patch enables later cleanup patches.

            * config/arm/arm_mve.h (__arm_vcmpeq*u*, __arm_vcmpne*u*): Call
            the 's' version of the builtin.
