Size matters in this case.
2. Remove the unused whichByte private function, which was also broken.
3. Remove the non-const overload of the getWord function, getWord() is
never used as an lvalue.
4. Rename some local variables for clarity (e.g. API -> Result).

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.

1. Make getMinValue() returns the right value.
2. Fix the ByteSwap() crash problem.
3. Make Postfix increment work correctly.
4. Fix some bugs in LogBase2, Hi/LoBits and UDiv.

1. Make all the operators use uppercase
2. Rename APIntRoundToDouble method just RoundToDouble, the APInt is
redundant.
3. Turn the class on for compilation.

add some signed/unsigned arithmetic operation functions into APInt.h to
handle the signed/unsigned issue. These functions will be defined inside a
namespace "APIntOps" which is inside llvm namespace.

It is a functional replacement for common case integer type like "unsigned",
"uint64_t", but also allows non-byte-width integer type and large integer
value types such as 3-bits, 15-bits, or more than 64-bits of precision. For
more details, see pr1043.
