// 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.
