-/// Return a vector that contains MemoryAccesses in the order in
-/// which they are executed.
-///
-/// The order is:
-/// - Implicit reads (BlockGenerator::generateScalarLoads)
-/// - Explicit reads and writes (BlockGenerator::generateArrayLoad,
-///   BlockGenerator::generateArrayStore)
-///   - In block statements, the accesses are in order in which their
-///     instructions are executed.
-///   - In region statements, that order of execution is not predictable at
-///     compile-time.
-/// - Implicit writes (BlockGenerator::generateScalarStores)
-///   The order in which implicit writes are executed relative to each other is
-///   undefined.
