15aab8a723 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.
This fixes numerous, but not all divide bugs.

ab2b2c827c Fix countLeadingZeros in the case that the bitwidth evenly divides the 
word size. This fixes all reads of uninitialized data (buffer over read)
and makes APInt.cpp memory clean, per valgrind. The only remaining
problem is division in a few cases.

f46847172a ELF / PIC requires GOT be in the EBX register during calls via PLT GOT pointer. 
Add implicit uses of EBX to calls to ensure liveintervalanalysis does not treat
the GOT in EBX move as dead upon definition.
This should fix PR1207.

385f7547b9 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.

9c0696f153 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.
