* config/arm/arm-c.c (arm_cpu_builtins): Use def_or_undef_macro
for __ARM_FP16_FORMAT_IEEE and __ARM_FP16_FORMAT_ALTERNATIVE.
Define __ARM_FP16_ARGS when appropriate.
* config/arm/arm.c (arm_invalid_parameter_type): Remove
declaration.
(arm_invalid_return_type): Likewise.
(TARGET_INVALID_PARAMETER_TYPE): Remove.
(TARGET_INVALID_RETURN_TYPE): Remove.
(aapcs_vfp_sub_candidate): Allow HFmode.
(aapcs_vfp_allocate): Add comment. Support HFmode.
(aapcs_vfp_allocate_return_reg): Likewise.
(struct aapcs_cp_arg_layout): Slightly reword comments for
is_return_candidate and allocate_return_reg.
(output_mov_vfp): Update assert.
(arm_hard_regno_mode_ok): Remove comment, update HF-mode
condition.
(arm_invalid_parameter_type): Remove.
(amr_invalid_return_type): Remove.
* config/arm/arm.h (TARGET_NEON_FP16): Fix definition.
* config/arm/arm.md (*arm32_movhf): Disable for TARGET_VFP.
* config/arm/vfp.md (*movhf_vfp): Enable for TARGET_VFP.
