This CL re-introduces useLHS because we don't want to suppress correct "declared but not used" errors for variables that only appear on the LHS of an assignment (using Checker.use would mark them as used). This CL also adjusts a couple of places where types2 differed from go/types (and suppressed valid "declared and not used" errors). Now those errors are surfaced. Adjusted a handful of tests accordingly.
