Yeah, it builds.

Will do it after that patch is landed.

Add a FIXME here, will do it in a follow-up -- as the symbol structure would be
changed.

`ToolExecutor` takes over the lifetime of `FrontendActionFactory`, there is no
straightforward way to get the internal `SymbolSlab` from the indexAction.
Changed to use `ClangTool`, since it would simplify the code a lot, and no
changes in `SymbolCollector`.

Yeah, the script is borrowed from other places for the fast prototype.
We can combine it into the `global-symbol-builder` binary. Done.
