71bd08f9be Clean up the divide and remainder logic a bit (exit early). Use more
meaningful variable names. Add comments to document the flow.

e81d2dad2c 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.

879dfe1c9c Use brute-force algorithm for to_string. It doesn't have to be efficient
at this point, it just needs to work so we can test things reliably.

db3faa64ee Make some minor improvements to APInt:
1. Make all the operators use uppercase
2. Rename APIntRoundToDouble method just RoundToDouble, the APInt is
   redundant.
3. Turn the class on for compilation.

d93f00c35d 1. Make APInt::shl work correctly and more efficiently.
2. Add functions to support the numberical conversion between APInt and
   double/float.

ff4304f824 Eliminates friend function declaration inside APInt, instead, adds public
methods as those global function's internal implementation.

0b706b18bd As Chris and Reid suggested, remove "isSigned" field from APInt, instead,
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.

fd43dcfc57 Add a class APInt to represent arbitrary precision constant integral values.
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.
