Wilco Dijkstra d2febe7c40 math: Improve layout of exp/exp10 data
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.
