PTAL. See attached bug. Bot_update runs "git clean -dff" which removes
third_party/icu on each update. This leads to unnecessary rebuilds in each run.
It is not removed if the parent dir is already ignored.

lgtm.

File .gitignore (right):

https://codereview.chromium.org/728983004/diff/1/.gitignore#newcode70
.gitignore:70: /third_party/icu
Now that you ignore the whole third_party/ dir, you may remove this entry and
the llvm one below?
