math: Improve layout of expf data
GCC aligns global data to 16 bytes if their size is >= 16 bytes. This patch changes the exp2f_data struct slightly so that the fields are better aligned. As a result on targets that support them, load-pair instructions accessing poly_scaled and invln2_scaled are now 16-byte aligned. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
