Different instructions order is caused by different GIMPLE statements order
after chkpopt pass.  Will prepare a fix for that.

Reduced test case:


module test
  implicit none

  type functions
  contains
    procedure :: get_pf
  end type

contains

  function get_pf(f)
    class     (functions)     :: f
    procedure (real), pointer :: get_pf
  end function

end module
