   A single OMP_FOR node represents an entire nest of collapsed
   loops; as noted below, some of its arguments are vectors of length
   equal to the collapse depth, and the corresponding elements holding
   data specific to a particular loop in the nest.  These vectors are
   numbered from the outside in so that the outermost loop is element 0.

   These constructs have seven operands:

   Operand 0: OMP_FOR_BODY contains the loop body.

   Operand 1: OMP_FOR_CLAUSES is the list of clauses
   associated with the directive.

   Operand 2: OMP_FOR_INIT is a vector containing iteration
   variable initializations of the form VAR = N1.

   Operand 3: OMP_FOR_COND is vector containing loop
   conditional expressions of the form VAR {<,>,<=,>=,!=} N2.

   Operand 4: OMP_FOR_INCR is a vector containing loop index
   increment expressions of the form VAR {+=,-=} INCR.

   Operand 5: OMP_FOR_PRE_BODY contains side effect code from
   operands OMP_FOR_INIT, OMP_FOR_COND and
   OMP_FOR_INCR.  These side effects are part of the
   OMP_FOR block but must be evaluated before the start of
   loop body.  OMP_FOR_PRE_BODY specifically
   includes DECL_EXPRs for iteration variables that are
   declared in the nested for loops.
   Note this field is not a vector; it may be null, but otherwise is
   usually a statement list collecting the side effect code from all
   the collapsed loops.

   Operand 6: OMP_FOR_ORIG_DECLS holds VAR_DECLS for the
   original user-specified iterator variables in the source code.
   In some cases, like C++ class iterators or range for with
   decomposition, the for loop is rewritten by the front end to
   use a temporary iteration variable.  The purpose of this field is to
   make the original variables available to the gimplifier so it can
   adjust their data-sharing attributes and diagnose errors.
   OMP_FOR_ORIG_DECLS is a vector field, with each element holding
   a list of VAR_DECLS for the corresponding collapse level.

   The loop index variable VAR must be an integer variable,
   which is implicitly private to each thread.  For rectangular loops,
   the bounds N1 and N2 and the increment expression
   INCR are required to be loop-invariant integer expressions
   that are evaluated without any synchronization.  The evaluation order,
   frequency of evaluation and side effects are otherwise unspecified
   by the standard.

   For non-rectangular loops, in which the bounds of an inner loop depend
   on the index of an outer loop, the bit OMP_FOR_NON_RECTANGULAR
   must be set.  In this case N1 and N2 are not ordinary
   expressions, but instead a TREE_VEC with three elements:
   the DECL for the outer loop variable, a multiplication
   factor, and an offset. */
