When robustBufferAccess is disabled, applications must guarantee that
no accesses will go out of bounds (statically or dynamically). For
accesses with static equal or sequential offsets this means they'll be
in-bounds for both active and inactive lanes. Hence we can omit all
lane masking on such load operations.
