GCC aligns global data to 16 bytes if their size is >= 16 bytes. This patch changes the exp_data struct slightly so that the fields are better aligned and without gaps. As a result on targets that support them, more load-pair instructions are used in exp. The exp benchmark improves 2.5%, "144bits" by 7.2%, "768bits" by 12.7% on Neoverse V2.
