     *
     * The basic idea is to keep track of whether the function has executed an
     * early return in a synthesized boolean variable (func->early_return_var)
     * and guard all code after the return on that variable being false. In the
     * case of loops we also replace the return with a break.
     *
     * The following algorithm loops over instructions in a block, recursing
     * into inferior CF blocks, until it hits one of the following two things:
     *
     * - A return statement. In this case, we remove everything after the return
     *   statement in this block. We have to stop and do this in a separate
     *   loop, because instructions must be deleted in reverse order (due to
     *   def-use chains.)
     *
     *   If we're inside of a loop CF block, we can instead just turn the
     *   return into a break, which offers the right semantics—except that it
     *   won't break out of nested loops.
     *
     * - A CF block which contains a return statement. After calling
     *   lower_return() on the CF block body, we stop, pull out everything after
     *   the CF instruction, shove it into an if block, and then lower that if
     *   block.
     *
     *   (We could return a "did we make progress" boolean like hlsl_transform_ir()
     *   and run this pass multiple times, but we already know the only block
     *   that still needs to be addressed, so there's not much point.)
     *
     *   If we're inside of a loop CF block, we again do things differently. We
     *   already turned any returns into breaks. If the block we just processed
     *   was conditional, then "break" did our work for us. If it was a loop,
     *   we need to propagate that break to the outer loop.
     *
     * We return true if there was an early return anywhere in the block we just
     * processed (including CF contained inside that block).
