Thanks for doing this!

Hmmm, it looks like both clients are now instantiating a gimple_ranger
just so they can pass it down to the path_range_query.  Maybe we
should  have another ctor with just:

path_range_query (bool resolve);

...and have it allocate its own ranger.

Does this seem like a useful improvement?  For that matter, resolve
should default to true.  The option is only there so the backward
threader can run in a "light" mode (early threading, etc).
