Subject: Flattening rewrite (#1201)

Rename flatten-control-flow to flatten, which now flattens everything, not just control flow, so e.g.

(i32.add
  (call $x)
  (call $y)
)
==>
(block
  (set_local $temp_x (call $x))
  (set_local $temp_y (call $y))
  (i32.add
    (get_local $x)
    (get_local $y)
  )
)

This uses more locals than before, but is much simpler and avoids a bunch of corner cases and fuzz bugs the old one hit. We can optimize later if necessary.
