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

* 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.

test suite but use "strange" integer bit widths.

Most tests written by Zhou Sheng, a few by me.

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.
