lgtm

So this patch is not really about aliases in general (since some were allowed)
but enabling aliases with underscores and other characters to work? Seems good,
but edge cases like this underscore the need to wait to ship this until we have
a spec and agreement on it.

Well it's both. Names with underscore should be allowed, and loose matching as
well, like PropertyValueAliases.txt describes.

And yes, this is not ready for shipping at all. Point of this experimental
implementation is to come across issues like these that we should bring up at
TC39 at some point.
