    i386: Split V2HImode *punpckwd to SSE instruction [PR101058]

    V2HImode *punpckwd should not be split to the insn that depends on
    TARGET_MMX_WITH_SSE, since the later is disabled on 32bit targets.

    Also return true early from ix86_vectorize_vec_perm_const when testing
    with V2HI mode.  *punpckwd can be used to implement all permutations.
