    testsuite/arm: Fix -mfloat-abi order in arm_v8_2a_bf16_neon_ok_nocache and arm_v8_2a_i8mm_ok_nocache
    
    Make the order in which we try -mfloat-abi options consistent with the
    other similar effective targets: try softfp first, then hard.
    
    This shows that a few tests implicitly rely on -mfloat-abi=hard, so we
    now check arm_hard_ok where needed.
    
    This makes these tests unsupported rather than fail on
    arm-linux-gnueabi.

            * lib/target-supports.exp
            (check_effective_target_arm_v8_2a_i8mm_ok_nocache): Fix
            -mfloat-abi= options order.
            (check_effective_target_arm_v8_2a_bf16_neon_ok_nocache): Likewise.
            * gcc.target/arm/bfloat16_scalar_1_1.c: Add arm_hard_ok effective
            target and -mfloat-abi=hard additional option.
            * gcc.target/arm/bfloat16_simd_1_1.c: Likewise.
            * gcc.target/arm/simd/bf16_ma_1.c: Likewise.
            * gcc.target/arm/simd/bf16_mmla_1.c: Likewise.
