[DAGCombiner] Bail out if BitWidthDiff > BitWidth when folding cltz(and) - BitWidthDiff (#166607)
Fixes https://github.com/llvm/llvm-project/issues/166596
We cannot use `APInt::isMask` if `numBits` exceeds the bitwidth of APInt
or `numBits` is zero. We avoid such a case by guaranteeing BitWidthDiff
< BitWidth.
