    	description:
    	go spec: Base comparison compatibility on assignment compatibility.
    
    	Specifically:
    	- Simplified definition of comparison compatibility and folded into
    	  section on comparison operators since it's only used there.
    
    	This is a small language change/cleanup. As a consequence:
    	- An interface value may now be compared against a non-interface value.
    	- Channels with opposite directions cannot be compared directly anymore
    	  (per discussion with rsc).

    but never implemented.
    
    Fixes #1070.
