Always look up verify_dirty literals from offsetsHEADtrimui-s

Literals are deduplicated, so there's no guarantee they will be stored
next to each other, even if they're written sequentially. verify_dirty
and get_bounds must use the offsets on each instruction, instead of
assuming values are stored sequentially.
