Temporarily revert 65975, which breaks the llvm-gcc build.
...
While the patch is clearly correct in itself, it's become
apparent other places are assuming debug intrinsics are
marked as touching memory...this needs more testing.

The DAG combiner was performing a BT combine. The BT combine had a value of -1,
...
so it changed it into a 31 via the TLO.ShrinkDemandedConstant() call. Then it
would go through the DAG combiner again. This time it had a value of 31, which
was turned into a -1 by TLI.SimplifyDemandedBits(). This would ping pong
forever.
Teach the TLO.ShrinkDemandedConstant() call not to lower a value if the demanded
value is an XOR of all ones.

From the code: "There are "Proj" libs (defined by the user's project) and "LLVM"

LLVM project.
