If the LHS is unassignable, there's no point in trying to make sure the RHS can be assigned to it or making sure they're realizable types. This is consistent with go/types. In particular, this prevents "1 = 2" from causing a panic when "1" still ends up with the type "untyped int", which is not realizable. Fixes #20813.
