    i386: Fix V8HF vector init under -mno-avx [PR 104664]

    For V8HFmode vector init with HFmode, do not directly emits V8HF move
    with subreg, which may cause reload to assign general register to move
    src.

            * config/i386/i386-expand.cc (ix86_expand_vector_init_duplicate):
              Use vec_setv8hf_0 for HF to V8HFmode move instead of subreg.
