Inheriting components & directives

[skirtles-code]

Version

3.0.0-rc.8

Reproduction link

https://jsfiddle.net/skirtle/p469rhax/9/

Steps to reproduce

Note the console error: 'Failed to resolve component: SayHi'.

If you change MyChild: CompB to MyChild: CompA it all works fine.

What is expected?

Extending a component should inherit and merge the components and directives options just like it did in Vue 2.

What is actually happening?

Only the render function gets inherited.

The example is intended to simulate a CLI project with a component that doesn't define its own <template> section.
