Modified Files:
	src/usr.bin/xlint/lint1: cgram.y

Log Message:
Prevent use of stale pointer for determining return type of ({ })
expressions.

Details:
lint did fail on constructs like

   struct foo *x;
   x = ({ struct foo *y; /* do stuff */; y;});

since it gave the whole ({ }) the same structure representing the
type as y, but that structure is reclaimed when y goes out of scope.
