I like that idea. :)

Also, it looks like I was mistaken: `CallTargetMap` is better off a `StringMap` than a `std::map<std::string, uint64_t>`. The difference was around 5%, which makes step one save us 17% of memory. Checked it in as r320764, as requested.

I'll do step 2 and step 3 in fresh, more targeted reviews.

Thanks again!
