[AArch64] Improve SVE handling of single-vector permutes
aarch64_vectorize_vec_perm_const was failing to set one_vector_p
if the permute had only a single input. This in turn was hiding
a problem in the SVE TBL handling: it accepted single-vector
variable-length permutes, but sent them through the general
two-vector aarch64_expand_sve_vec_perm, which is only set up
to handle constant-length permutes.
