Performance optimization means not every path will be traversed.
Instead of updating parents via the path, perform a 2nd bottom-up walk
after the top-down walk to propagate the new resolutions to parents.
Note: the 2nd walk method will add resolutions to statically linked
libraries etc. at deeper levels, but those do not affect what gets
reported. In particular, note that test data for dumpresolutions
changes, but none of the test data for listshare, checkshare etc.
changes.

Includes the below command-line tool:
dumpresolutions outputs the resulting set of resolutions after the
bottom-up and top-down resolves, or after joining 1 or more condition
walks.
