  Cover vector dynamic indexing case in SplitSequenceOperator
  
  Vectors or matrices that are dynamically indexed as a part of an
  l-value generate new statements in the RemoveDynamicIndexing AST
  transformation step. SplitSequenceOperator needs to detect this case
  and split the sequence operator before statements are generated from
  its operands to ensure the correct order of execution.

  // SplitSequenceOperator is an AST traverser that detects sequence operator expressions that
  // go through further AST transformations that generate statements, and splits them so that
  // possible side effects of earlier parts of the sequence operator expression are guaranteed to be
  // evaluated before the latter parts of the sequence operator expression are evaluated.
