[APInt] Add a isOneValue method that can determine if a number is 1 by only using getActiveBits/countLeadingZeros
Previously you would have to use operator==(uint64_t) which does the getActiveBits call and a uint64_t comparison. But we can get all we need to know from the getActiveBits call.
This method will be used in another commit.
