[4/6] Optionally pick the cheapest loop_vec_info

This patch adds a mode in which the vectoriser tries each available base vector mode and picks the one with the lowest cost. For now the behaviour is behind a default-off --param, but a later patch enables it by default for SVE. The patch keeps the current behaviour of preferring a VF of
