Fixes INDEX_op_rotli_vec for aarch64 host, where the 3rd argument is an integer, not a temporary, which now tickles an assert added in e89b28a6350. Previously, the value computed into v2 would be garbage for rotli_vec, but as the value was unused it caused no harm. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
