[Bug fortran/30802] out of bounds error array I/O not picked up with -fbounds-check

I think the problem is that we don't insert bounds checking
in gfc_conv_expr_descriptor.

Another test case:

$ cat index.f90 
module bar
contains
  subroutine foo(a)
  real, dimension(:) :: a
  a = 3.
  end subroutine foo
end module bar
program main
  use bar
  real, dimension(2,2) :: a
  n = 3
  call foo(a(n,:))
end program main
$ gfortran index.f90 
$ gfortran -fbounds-check index.f90 
$ ./a.out
