Check whether a vector of QIs can store all indices
The patch to remove the vec_perm_const optab checked whether replacing
a constant permute with a variable permute is safe, or whether it might
truncate the indices. This patch adds a corresponding check for whether
variable permutes can be lowered to QImode-based permutes.

* optabs-query.c (can_vec_perm_var_p): Check whether lowering
to qimode could truncate the indices.
