[Bug tree-optimization/19126] Missed IV optimization (redundant instruction in loop)

This shows up a lot in fortran code like the following (and yes I copied this from some where and 
reduced it):
SUBROUTINE d ( a, b, ndim )
IMPLICIT NONE
INTEGER, INTENT(IN) :: ndim
REAL,DIMENSION(ndim,ndim) :: a
REAL,DIMENSION(ndim,ndim) :: b
b(1,:) = a(2,:)
END SUBROUTINE d
