Andrea Gussoni d4d5e1a966 GenerateAst: rewrite SwitchNode tiling ...

Perform a complete rewrite of the `SwitchNode` tiling routine.
The tiling now works in the following way:
- When encountering a node which will produce a `SwitchNode` (either a
  standard `switch` or a dispatcher `switch`), we look for the following
  situations:
  1) We have a node, a successor (case) of the `switch`, which in turn
     is the successor of all the other successors (cases) of the
     `switch`.
  2) We have a node, not a successor (case) of the `switch`, which is
     the successor of all the successors (cases) of the `switch`.
- If we find such candidate node, this node will be the fallthrough of
  the `switch`. In addition, depending on whether the `switch` dominates
  the candidate fallthrough, we can incorporate it as the immediate
  successor of the `SwitchNode` we are building.
- There is currently an exception to the above, due to how we currently
  handle weaved `switch`es. In such cases, we mandate that the weaved
  `switch` is nested inside the main corresponding `switch`. For this
  reason, we have a special casing handling the "all inlined but one"
  situation in the new code, while this part could in theory be merged
  in the common criterion below, at the cost of dropping the invariant
  of the nesting of weaved switch`es.
