  vkd3d-shader/hlsl: Implement normalization of binary expressions.
  
  We normalize binary expressions by attempting to group constants
  together, in order to facilitate further simplification of the
  expressions.
  
  For any binary operator OP, non-constants x, y, and constants a, b, we
  apply the following rewrite rules:
  
    a OP x -> x OP a, if OP is commutative.
  
    (x OP a) OP b -> x OP (a OP b), if OP is associative.
  
    (x OP a) OP y -> (x OP y) OP a, if OP is associative and commutative.
  
    x OP (y OP a) -> (x OP y) OP a, if OP is associative.
  
  Note that we consider floating point operations to be
  non-associative.
