A SMETANA to Infinity! quine

The broad structure of the quine is as follows.

Step n+8488. Swap step n with step n+1.
Step 17426. Go to step 150.
   This sets up code enterable at step 8939 that performs a cyclic shift of
   steps 451 to 8938.
   
Step 0001. [...] Step 0451.
   The main program that is responsible for iterating over the data twice,
   once to reproduce itself, and once to reproduce the data.
   
Step 0452. [...] Step 8938.
   Data bits (one bit per instruction) encoded as either `Swap step 8 with
   step 9.` for true, or as `Swap step 8 with step 8.` for false.

The quine is generated by running Quine.hs, followed by running its output once in a SMETANA to Infinity! interpreter.

-- e:  swap m f   -- undo swap

-- Booleans

-- Booleans are encoded as a swap instruction. They have two states:
-- b:  swap 8 9 -- if b = true  | b:  swap 8 8 -- if b = false

-- If-then-else can be implemented based on the idea of observing the
-- different effects of `swap 8 9` and `swap 8 8`; this involves patching
-- locations 8 and 9.
