I really think you're better off using int64_t (== java's long) consistently
everywhere. It makes the whole thing easier to read and reason about, and the
"waste" is negligible.

Integer types are just plain trouble in C++, and especially across languages.
Consistent is simple is good.

The windows bots fail to compile because int64_t is not defined. Is that
expected? I can't find a good header to include for defining it. Inside of
content/ it seems mostly the pepper code that uses int64_t. Any ideas?
