testsuite/arm: Fix -mfloat-abi order in arm_v8_2a_bf16_neon_ok_nocache and arm_v8_2a_i8mm_ok_nocache

Browse source 
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.

	gcc/testsuite/
	* 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.
	* gcc.target/arm/simd/vdot-2-1.c: Likewise.
	* gcc.target/arm/simd/vdot-2-2.c: Likewise.
