According to the specification in ARM-software/acle#309 this adds the intrinsics ``` svbfloat16x2_t svclamp[_single_bf16_x2](svbfloat16x2_t zd, svbfloat16_t zn, svbfloat16_t zm) __arm_streaming; svbfloat16x4_t svclamp[_single_bf16_x4](svbfloat16x4_t zd, svbfloat16_t zn, svbfloat16_t zm) __arm_streaming; ``` These are available only if __ARM_FEATURE_SME_B16B16 is enabled.
