[Bug tree-optimization/21030] [4.1 Regression] ICE in set_value_range building 176.gcc with -O2

This is a shorter version of the Fortran code.  The bug is now
critical to gfortran because almost all Fortran codes contain
nested do loops.

      SUBROUTINE CHER2K(N, C, LDC)

      INTEGER I, J, N, LDC
      COMPLEX C(LDC,*)

      DO 20, J = 1, N
         DO 10, I = 1, J
            C(I,J) = (0.0E+0, 0.0E+0)
   10    CONTINUE
   20 CONTINUE
      END
