Proposal: allow primitives to be explicitly returned from constructors

Here's my proposal:
In constructors, currently, non-objects are replaced with `this`.
Here's what I think it should be replaced with:
1. When calling the constructor, if `undefined` is returned and
`new.target` is not `undefined`, return `this` instead. This is for
compatibility and ease of implementation.
1. When calling the constructor, if anything else is returned, return
that value in raw form.
I know this is very *likely* very breaking, but I wonder if it would
In case you're curious what this would change in the spec, it would
change [section 9.2.2], step 13.a-13.c to this:
a. If result.[[Value]] is not `undefined`, return
b. If kind is `"base"`, return NormalCompletion(thisArgument).
