3573b012d3 1. Fix a carry out problem in add if destination and x point to the same 
memory (as done in fromString).

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.
This fixes numerous, but not all divide bugs.

d51b03d452 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.
