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.
