cbff120eeb When converting from 64 to 32-bits, use the actual number of words to 
extract the value, not the number of words implied by the active bits.

c4662ad089 1. Add a dump() method for faster debugging. 
2. Change 0 initialization of union to larger component so all is zeroed.
3. Fix the borrow logic in subtraction so it works for > 128 bits.
4. Rewrite fromString to use a simpler but correct algorithm and also to
   not set the bit width contrary to the user's request.
5. Optimize toString a bit by making it only do one Knuth divide per
   iteration instead of two.

With these changes, all arithmetic passes (verified by pari/GP) up to
1024 bits except for certain division cases.

80b41ab5f7 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.

78e1ec0122 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.

d22266f456 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

something like assert(0 && "foo"). This patch fixes all the cases that a
quick grep found.
