[APInt] Simplify the zext and sext methods This replaces a hand written copy loop with a call to memcpy for both zext and sext. For sext, it replaces multiple if/else blocks propagating sign information forward. Now we just do a copy, a sign extension on the last copied word, a memset, and clearUnusedBits.
