This fixes numerous, but not all divide bugs.

and makes APInt.cpp memory clean, per valgrind. The only remaining
problem is division in a few cases.

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.

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.
