Merge #773

773: Crash fixes r=matklad a=flodiebold

This fixes a bunch of crashes found while running type inference on the whole rustc repo :sweat_smile: 
 - avoid infinite recursion with ref bind patterns
 - avoid another infinite recursion
 - handle literal patterns, add a new LITERAL_PAT syntax node for this
 - fix an expect that's wrong on some invalid code
