Dinesh Dwivedi 3217b6c661 Added select flavour for ABS and NEG(ABS) 
This patch can identify 
  ABS(X) ==> (X >s 0) ? X : -X and (X >s -1) ? X : -X
  ABS(X) ==> (X <s 0) ? -X : X and (X <s 1) ? -X : X
  NABS(X) ==> (X >s 0) ? -X : X and (X >s -1) ? -X : X
  NABS(X) ==> (X <s 0) ? X : -X and (X <s 1) ? X : -X
  
and can transform
  ABS(ABS(X)) -> ABS(X)
  NABS(NABS(X)) -> NABS(X)
