Added a new refactoring warning, 'simplifiable-if-statement'

This is used when an if statement could be reduced to a boolean evaluation
of its test, as seen in this example:

   if some_cond:
      return True
   else:
      return False

   could be reduced to `return bool(some_cond)`

Closes issue #698.

     * Added a new refactoring warning, 'too-many-boolean-expressions',
       used when a if statement contains too many boolean expressions,
       which makes the code less maintainable and harder to understand.
