///
/// Loop analyses are allowed to make some simplifying assumptions:
/// 1) Loops are, where possible, in simplified form.
/// 2) Loops are *always* in LCSSA form.
/// 3) A collection of analysis results are available:
///    - LoopInfo
///    - DominatorTree
///    - ScalarEvolution
///    - AAManager
///
/// The primary mechanism to provide these invariants is the loop pass manager,
/// but they can also be manually provided in order to reason about a loop from
/// outside of a dedicated pass manager.
