event section ID

[binji]

The event section is currently specified as id 12. The bulk memory proposal is also going to add a new section (see WebAssembly/bulk-memory-operations#42), and will likely ship first. Should it have 12 instead so we don't have a gap in the known section ids? Or does it even matter?

I don't think it matters a lot, but it may look weird. I don't mind change the event section to 13. We need to change the spec text, LLVM implementation, and V8 implementation. I can take care of the first two. @mstarzinger, could you change the event section ID in V8?

[mstarzinger]

Yes, that is an easy change. Coincidentally it used to be 13 in V8 until a couple of days ago because I originally chose the value at random before it was specified in the proposal. I'll keep V8 updated. Easy change similar to this one: https://chromium.googlesource.com/v8/v8/+/69ab6954b12091b7252ad79d5e940a9ed4244841
