Description

Functions such as rec_init_offsets_comp_ordinary() are using some conditional branches where bitwise arithmetics would work. Furthermore, some tweaks to silence -Wconversion in GCC versions 6 to 9 (~~MDEV-21907~~) might cause some performance degradation, or at least make the code harder to read.
