That's not okay: If you have
integer, allocatable :: a(:), b(:)
one has an EXPR_STRUCTURE for "[a,b]" but not a constant expression. One has to
do a deep check. Well, gfc_is_constant_expr() is supposed to do this.
(Or should gfc_check_init_expr be used? I always confuse the two. For F90/F95
it makes a difference, for F200x it doesn't, and gfortran's usage is a mess.)
