We can still deal with BFmode permutation the same way as HFmode, so
the change in ix86_vectorize_vec_perm_const can be preserved.

Hi,
According to the instruction spec of AVX512BF16, the convert from float
to BF16 is not a simple truncation. It has special handling for
denormal/nan, even for normal float it will add an extra bias according
to the least significant bit for bf number. This means we cannot use the
