Convert remaining passes to get_range_query.

This patch converts the remaining users of get_range_info and
get_ptr_nonnull to the get_range_query API.

No effort was made to move passes away from VR_ANTI_RANGE, or any other
use of deprecated methods.  This was a straight up conversion to the new
API, nothing else.
