import of class declared in translation unit: allowed

Due to a clarification in the spec (see 4661751) it is legal to import
a type declared in the same translation unit, but javac rejects that
code. Javac should accept that code.

     1 package p1;
     2 import p1.T;
     3
     4 class T {
     5 public static void main(String[] args) {
     6 }
     7 }
