Use vec<> for constant permute masks
This patch makes can_vec_perm_p & co. take a vec<>, wrapped in new
typedefs vec_perm_indices and auto_vec_perm_indices. There are two
reasons for doing this for SVE:
(1) it means that the number of elements is bundled with the elements
themselves, and is obviously constant.
(2) it makes it easier to change the "unsigned char" element type to
something wider.
Changing the target hook is left as follow-on work.
