Add clangTooling dependency to fix the build.

Summary

Fixes https://reviews.llvm.org/D59371, which broke the build for shared libraries.

Nope, it won't work. There is a cyclic dependency, unfortunately. clangTooling depends on clangToolingRefactor already. You need to revert your commit and refactor it to remove the cyclic dependency.

I see. I've never reverted before and I can't seem to find any instructions for doing so (only some offhand mentions). If there's a doc on this, can you please link me to it?

Thanks!

I can revert it for you, if you want
