The vec_perm code falls back to doing byte-level permutes if element-level permutes aren't supported.
qimode_for_vec_perm
The vec_perm code falls back to doing byte-level permutes if
element-level permutes aren't supported. There were two copies
of the code to calculate the mode, and later patches add another,
so this patch splits it out into a helper function.
