My plan is to start adding the subdirectories that are clean, until we get gpu
passing fully. So eventually, //gpu:* will be removed and //gpu/* will take it
place.

I extracted this from https://codereview.chromium.org/1109473004/, since the
client_sources/service_sources is issue is much bigger and needs to be addressed
separately as it will required code surgery.
