[ARM] Add V8HFmode and float16x8_t type

Browse Source 
* config/arm/arm.h (VALID_NEON_QREG_MODE): Add V8HFmode.

	* config/arm/arm.c (arm_vector_mode_supported_p): Support V8HFmode.

	* config/arm/arm-builtins.c (v8hf_UP): New.
	(arm_init_simd_builtin_types): Initialise Float16x8_t.

	* config/arm/arm-simd-builtin-types.def (Float16x8_t): New.

	* config/arm/arm_neon.h (float16x8_t): New typedef.
