[Chris Lattner]

Changes in directory llvm/test/Regression/Transforms/InstCombine:

add.ll updated: 1.11 -> 1.12
and.ll updated: 1.14 -> 1.15
cast.ll updated: 1.12 -> 1.13
set.ll updated: 1.11 -> 1.12
sub.ll updated: 1.11 -> 1.12
xor.ll updated: 1.3 -> 1.4

---
Log message:

Reorganize tests because we no longer cannonicalize X != 0 -> cast X to bool
In fact, we plan to eliminate cast to bool entirely.
