Yes the clicking around on semantic links on source.chromoum.org is served off of an index built by the Kythe team at Google.
The internal Kythe has some interesting bits (mostly around scaling) that aren't open sourced, but it's probably doable to run something on chromium scale without too much of that.
The grep/search box up top is a different index, maintained by a different team.
