First version that can process arith.cpp test case up to 1024 bits:
...
1. Ensure pVal is set to 0 in each constructor.
2. Fix roundToDouble to make correct calculations and not read beyond the
end of allocated memory.
3. Implement Knuth's "classical algorithm" for division from scratch and
eliminate buffer overflows and uninitialized mememory reads. Document
it properly too.
4. Implement a wrapper function for KnuthDiv which handles the 64-bit to
32-bit conversion and back. It also implement short division for the
n == 1 case that Knuth's algorithm can't handle.
5. Simplify the logic of udiv and urem a little, make them exit early, and
have them use the "divide" wrapper function to perform the division
or remainder operation.
6. Move the toString function to the end of the file, closer to where
the division functions are located.
Note: division is still broken for some > 64 bit values, but at least it
doesn't crash any more.

Implement support for non-standard integer bit widths of any size. The

rules alignment is to pick the alignment that corresponds to the smallest
specified alignment that is larger than the bit width of the type or the
largest specified integer alignment if none are larger than the bitwidth
of the type. For the byte size, the size returned is the next larger
multiple of the alignment for that type (using the above rule). This patch
also changes bit widths from "short" to "uint32_t" to ensure there are
enough bits to specify any bit width that LLVM can handle (currently 2^23);
16-bits isn't enough.

6. Simplify the logical operator code because bitwidths must be the same.
7. Fix indentation per coding standards.
8. Use exit-early style to reduce indentation in several functions.

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.

While preparing http://llvm.org/PR1198 I noticed several asserts
protecting unprepared code from i128 types that weren't actually failing
when they should because they were written as assert("foo") instead of
something like assert(0 && "foo"). This patch fixes all the cases that a
quick grep found.

Make some minor improvements to APInt:

3. Turn the class on for compilation.
