* Convert the last use of a uint64_t that should have been an APInt.
* Change ComputeMaskedBits to have a const reference argument for the Mask
  so that recursions don't cause unneeded temporaries. This causes temps
  to be needed in other places (where the mask has to change) but this
  change optimizes for the recursion which is more frequent.
* Remove two instances of &ing a Mask with getAllOnesValue. Its not
  needed any more because APInt is accurate in its bit computations.
* Start using the getLowBitsSet and getHighBits set methods on APInt
  instead of shifting. This makes it more clear in the code what is
  going on.

Allow the b/h/w/k constraints to be applied to values that have multiple alternatives, and end up not being registers.

Convert some calls to ConstantInt::getZExtValue() into getValue() and
use APInt facilities in the subsequent computations.

Add final support to get the QT example to compile.

* APIntify visitAdd and visitSelectInst
* Remove unused uint64_t versions of utility functions that have been
  replaced with APInt versions.
This completes most of the changes for APIntification of InstCombine. This
passes llvm-test and llvm/test/Transforms/InstCombine/APInt.

operators.

infinity in other cases. Passes CFP2006 (not that that says much).

Analyze GEPs. If the indices are all zero, transfer whether the pointer is
known to be not null through the GEP.

Add a few more cases for xor and shift instructions.

* Fix some indentation and comments in InsertRangeTest
* Add an "IsSigned" parameter to AddWithOverflow and make it handle signed
  additions. Also, APIntify this function so it works with any bitwidth.
* For the icmp pred ([us]div %X, C1), C2 transforms, exit early if the
  div instruction's RHS is zero.
* Finally, for icmp pred (sdiv %X, C1), -C2, fix an off-by-one error. The
  HiBound needs to be incremented in order to get the range test correct.
