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.
