Craig Topper d49344495d [KnownBits] Add bit counting methods to KnownBits struct and use them where possible 
This patch adds min/max population count, leading/trailing zero/one bit counting methods.

The min methods return answers based on bits that are known without considering unknown bits. The max methods give answers taking into account the largest count that unknown bits could give.
