This reverts commit 7da9850643f55335a13a4663d226c73d0ac4d3b1. 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.

	3cbb27a1	2016-07-14T11:55:48		Simplify loop conditions so that they won't generate statements Introduce an AST traverser that can move the evaluation of certain types of loop conditions and loop expressions inside the loop. This way subsequent AST transformations don't have to worry about cases where they have to insert new statements to implement a loop condition or expression. This includes the revert of "Unfold short-circuiting operators in loop conditions correctly". The new traverser covers the loop cases that used to be handled in UnfoldShortCircuitToIf.
