This PR adds a parser option to disable parsing of Annex B features. Annex B syntax is not portable and developers are discouraged from using it. Additionally, some valid JS code becomes invalid when Annex B is enabled (if(a<!--b) {}).

It's a parser option and not a plugin because plugins are opt-in, while we currently parse Annex B by default so this can only be opt-out. I would like to make it a plugin in Babel 8.

Note that @babel/parser doesn't validate regex syntax, so this PR does not affect the various Annex B regex extensions.

The changes LGTM. If we would like annexB: false to be the Babel 8 default, we can actually start phasing it out from the next minor: we can recover from the annexB and emit warnings such as

you are using legacy annexB language features. It will be disabled by default in Babel 8, before you migrate your codebase, you can specify parserOpts: { annexB: true } in your Babel config to suppress this warning.

For most users who, assumingly, don't use annexB features, they don't have to worry about the annexB parser breaking changes at all if they upgrade from the latest Babel 7 version.

It's good enough for me as a parser option, though I wouldn't block changes to a plugin in babel8.

we can recover from the annexB and emit warnings such as

The only problem is that error recovery is not enabled by default, so that would be an hard error for most users.
