+// 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.
