            PR target/103571
            * config/i386/i386.h (VALID_AVX256_REG_MODE): Add V16HFmode.
            (VALID_AVX256_REG_OR_OI_VHF_MODE): Replace with ...
            (VALID_AVX256_REG_OR_OI_MODE): ... this.  Remove V16HFmode.
            (VALID_AVX512F_SCALAR_MODE): Remove HImode and HFmode.
            (VALID_AVX512FP16_SCALAR_MODE): New.
            (VALID_AVX512F_REG_MODE): Add V32HFmode.
            (VALID_SSE2_REG_MODE): Add V8HFmode, V4HFmode and V2HFmode.
            (VALID_SSE2_REG_VHF_MODE): Remove.
            (VALID_INT_MODE_P): Add V2HFmode.
            * config/i386/i386.c (function_arg_advance_64):
            Remove explicit mention of V16HFmode and V32HFmode.
            (ix86_hard_regno_mode_ok): Remove explicit mention of XImode
            and V32HFmode, use VALID_AVX512F_REG_OR_XI_MODE instead.
            Use VALID_AVX512FP_SCALAR_MODE for TARGET_aVX512FP16.
            Use VALID_AVX256_REG_OR_OI_MODE instead of
            VALID_AVX256_REG_OR_OI_VHF_MODE and VALID_SSE2_REG_MODE instead
            of VALID_SSE2_REG_VHF_MODE.
            (ix86_set_reg_reg_cost): Remove usge of VALID_AVX512FP16_REG_MODE.
            (ix86_vector_mode_supported): Ditto.
