The long type in WebIDL <https://heycam.github.io/webidl/#idl-long> corresponds
to int32_t in C++, and internally int is used if you look at at e.g.
Element.scrollWidth or the generated code.

Done.

The int32_t mention was to point out that WebIDL's long has a very specific
range, but nevertheless int should be used internally.
