+/// Class to represented the control flow structure of an OpenMP canonical loop.
+///
+/// The control-flow structure is standardized for easy consumption by
+/// directives associated with loops. For instance, the worksharing-loop
+/// construct may change this control flow such that each loop iteration is
+/// executed on only one thread. The constraints of a canonical loop in brief
+/// are:
+///
+///  * The number of loop iterations must have been computed before entering the
+///    loop.
+///
+///  * Has an (unsigned) logical induction variable that starts at zero and
+///    increments by one.
+///
+///  * The loop's CFG itself has no side-effects. The OpenMP specification
+///    itself allows side-effects, but the order in which they happen, including
+///    how often or whether at all, is unspecified. We expect that the frontend
+///    will emit those side-effect instructions somewhere (e.g. before the loop)
+///    such that the CanonicalLoopInfo itself can be side-effect free.
+///
+/// Keep in mind that CanonicalLoopInfo is meant to only describe a repeated
+/// execution of a loop body that satifies these constraints. It does NOT
+/// represent arbitrary SESE regions that happen to contain a loop. Do not use
+/// CanonicalLoopInfo for such purposes.
+///
+/// The control flow can be described as follows:
+///
+///     Preheader
+///        |
+///  /-> Header
+///  |     |
+///  |    Cond---\
+///  |     |     |
+///  |    Body   |
+///  |    | |    |
+///  |   <...>   |
+///  |    | |    |
+///   \--Latch   |
+///              |
+///             Exit
+///              |
+///            After
+///
+/// The loop is thought to start at PreheaderIP (at the Preheader's terminator,
+/// including) and end at AfterIP (at the After's first instruction, excluding).
+/// That is, instructions in the Preheader and After blocks (except the
+/// Preheader's terminator) are out of CanonicalLoopInfo's control and may have
+/// side-effects. Typically, the Preheader is used to compute the loop's trip
+/// count. The instructions from BodyIP (at the Body block's first instruction,
+/// excluding) until the Latch are also considered outside CanonicalLoopInfo's
+/// control and thus can have side-effects. The body block is the single entry

+/// TODO: Consider adding another standardized BasicBlock between Body CFG and
+/// Latch to guarantee that there is only a single edge to the latch. It would
+/// make loop transformations easier to not needing to consider multiple
+/// predecessors of the latch (See redirectAllPredecessorsTo) and would give us
+/// an equivalant to PreheaderIP, AfterIP and BodyIP for inserting code that
+/// executes after each body iteration.
+///
+/// There must be no loop-carried dependencies through llvm::Values. This is
+/// equivalant to that the Latch has no PHINode and the Header's only PHINode is
+/// for the induction variable.
+///
+/// All code in Header, Cond, Latch and Exit (plus the terminator of the
+/// Preheader) are CanonicalLoopInfo's responsibility and their build-up checked
+/// by assertOK(). They are expected to not be modified unless explicitly
+/// modifying the CanonicalLoopInfo through a methods that applies a OpenMP
+/// loop-associated construct such as applyWorkshareLoop, tileLoops, unrollLoop,
+/// etc. These methods usually invalidate the CanonicalLoopInfo and re-use its
+/// basic blocks. After invalidation, the CanonicalLoopInfo must not be used
+/// anymore as its underlying control flow may not exist anymore.
+/// Loop-transformation methods such as tileLoops, collapseLoops and unrollLoop
+/// may also return a new CanonicalLoopInfo that can be passed to other
+/// loop-associated construct implementing methods. These loop-transforming
+/// methods may either create a new CanonicalLoopInfo usually using
+/// createLoopSkeleton and invalidate the input CanonicalLoopInfo, or reuse and
+/// modify one of the input CanonicalLoopInfo and return it as representing the
+/// modified loop. What is done is an implementation detail of
+/// transformation-implementing method and callers should always assume that the
+/// CanonicalLoopInfo passed to it is invalidated and a new object is returned.
+/// Returned CanonicalLoopInfo have the same structure and guarantees as the one
+/// created by createCanonicalLoop, such that transforming methods do not have
+/// to special case where the CanonicalLoopInfo originated from.
+///
+/// Generally, methods consuming CanonicalLoopInfo do not need an
+/// OpenMPIRBuilder::InsertPointTy as argument, but use the locations of the
+/// CanonicalLoopInfo to insert new or modify existing instructions. Unless
+/// documented otherwise, methods consuming CanonicalLoopInfo do not invalidate
+/// any InsertPoint that is outside CanonicalLoopInfo's control. Specifically,
+/// any InsertPoint in the Preheader, After or Block can still be used after
+/// calling such a method.
