There is just one version now, called IsPowerOfTwo. It accepts any
integral type.
There is one slight semantical change: Called with kMinInt, it
previously returned true, because the argument was implicitly casted to
an unsigned. It's now (correctly) returning false, so I had to add
special handlings of kMinInt in machine-operator-reducer before calling
IsPowerOfTwo on that value.
