  // RewriteRepeatedAssignToSwizzled.h: Rewrite expressions that assign an assignment to a swizzled
  // vector, like:
  //     v.x = z = expression;
  // to:
  //     z = expression;
  //     v.x = z;
  //
  // Note that this doesn't handle some corner cases: expressions nested inside other expressions,
  // inside loop headers, or inside if conditions.
