Change permute index type to unsigned short
This patch changes the element type of (auto_)vec_perm_indices from
unsigned char to unsigned short. This is needed for fixed-length
2048-bit SVE. (SVE is variable-length by default, but it's possible
to ask for specific vector lengths if you want to.)

* target.h (vec_perm_indices): Use unsigned short rather than
unsigned char.
(auto_vec_perm_indices): Likewise.
* config/aarch64/aarch64.c (aarch64_vectorize_vec_perm_const_ok):
Use unsigned int rather than unsigned char.
* config/arm/arm.c (arm_vectorize_vec_perm_const_ok): Likewise.
