the caller may not know (or care to check) that the number of bits set is
zero.

they should have used the uint64_t constructor. This avoids causing
undefined results via shifts by the word size when the bit width is an
exact multiple of the word size.

already covered by getLowBitsSet (i.e. when loBits==0). Consequently, remove
the default value for loBits and reorder the arguments to the more natural
loBits, hiBits order. This makes it more clear that this function is for bit
groups in the middle of the bit width and not towards one end or the other.

1. Group similar methods into doxygen groups
2. Reorganize the groups into a consist flow.
3. Significantly improve the quality of the documentation on several methods
4. Rewrite srem and sdiv to eliminate a copy and improve readability.
5. Eliminate unneeded forward references.

* 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.
