1. Fix some indentation and variable names in the get{Min,Max}Value methods.

2. Implement toString for power-of-2 radix without using divide and always
printing full words. This allows hex/binary to look at the bit
respresentation of the APInt as well as avoid bugs in divide.

Review changes:
...
1. Function style changes.
2. 80-col violations.
3. Better names for things.
4. Arrange constructors so they all take bit width first.
5. Add named signed and unsigned comparison functions and remove the
corresponding operators.
6. Remove operator&& and operator|| but provide a getBoolValue function which
converts to bool as comparison against 0. This allows the normal && and
|| operators to be used as if (X.getBoolValue() && Y.getBoolValue())
Note: this still doesn't function 100% yet. I'm working on the bugs now.
