[PATCH GCC][3/7]Don't skip renaming PHIs in loop nest with only one inner loop

Hi, Function rename_variables_in_bb skips renaming PHI nodes in loop nest if the outer loop has only one inner loop. This breaks loop nest distribution when inner loop has PHI node initialized from outer loop's variable. Unfortunately, I lost the original C code illustrating the issue. Now it is
