Hm, I still don't like having to manually mark each library as allowing
instrumenting. Is there much cost to instrumenting libraries when we don't need
to? We could guard it on <(chromium_code) so that it isn't used for third_party
libraries.

If there is significant cost to that, then this is fine. 

The name implies that setting this to 1 enables emma instrumentation, but it
also depends on <(emma_coverage). If you can think of a name that makes that
clear, that would be great, but isn't required.

Ah I didn't notice the chromium_code variable before. Instrumenting all java
libs with that variable set actually sounds perfect. I'm going to switch over to
that.
