This patch makes TARGET_VECTORIZE_VEC_PERM_CONST_OK take the permute
vector in the form of a vec_perm_indices instead of an unsigned char *.
It follows on from the recent patch that did the same in target-independent
code.
It was easy to make ARM and AArch64 use vec_perm_indices internally
as well, and converting AArch64 helps with SVE. I did try doing the same
for the other ports, but the surgery needed was much more invasive and
much less obviously correct.
