Sam Tobin-Hochstadt d589f6a8ed Avoid problematic reordering of Or patterns.
This makes two changes to `(or ...)` pattern compilation.

* Avoid reordering the individual elements of an `or` pattern.
  Since this reordering has broken programs with `and` patterns,
  avoid it here as well.

* Avoid re-ordering sets of patterns that _contain_ an `or`. This
  is not semantically important for match itself, but Typed Racket
  relies on the previous behavior.

  Closes racket/typed-racket#150.
