[Bug tree-optimization/27725] error in loop invariant motion tranformation

Actually Loop invariant motion is still doing its job even if the asm does not
clober memory, it does read memory and you did not record that.  The correct
way to fix this is:
  asm volatile("\tmovl (%1), %0\n"
               "\tincl %0\n"
               :"=r" (res)  : "r" (pi), "m" (*pi)) ;
