    i386: Fix wrong codegen for V8HF move without TARGET_AVX512F

    Since _Float16 type is enabled under sse2 target, returning
    V8HFmode vector without AVX512F target would generate wrong
    vmovdqa64 instruction. Adjust ix86_get_ssemov to avoid this.

            * config/i386/i386.c (ix86_get_ssemov): Adjust HFmode vector
            move to use the same logic as HImode.
