In commit 7390e0e9ab8475, we added support for SME loads and stores. Unlike SVE loads and stores, these include handling of 128-bit elements. The SME load/store functions call down into the existing sve_cont_ldst_elements() function, which uses the element size MO_* value as an index into the pred_esz_masks[] array. Because this code path now has to handle MO_128, we need to add an extra element to the array.This bug was spotted by Coverity because it meant we were reading off the end of the array.
