vkd3d-shader/hlsl: Fold some general unary identities.

Browse Source 
The following unary identities are applied:

  ||x|| -> |x|
  |-x| -> |x|
  ~(~x) -> x
  f(g(x)) -> g(x), where f(), g() are floor() or ceil() functions.
  -(-x) -> x
  !!x -> x
  !(x == y) -> x != y, !(x < y) -> x >= y, etc (for integers).
