Shuxin Yang a0c9939873 Perform factorization as a last resort of unsafe fadd/fsub simplification. ...

Rules include:
  1)1 x*y +/- x*z => x*(y +/- z) 
    (the order of operands dosen't matter)

  2) y/x +/- z/x => (y +/- z)/x 

 The transformation is disabled if the new add/sub expr "y +/- z" is a 
denormal/naz/inifinity.
