[PATCH] D17267: [DemandedBits] Introduce a getMinimumBitWidth() member function

[Hal Finkel via llvm-commits]

hfinkel added a comment.

I'll look at this in detail as soon as I can. In the mean time, a high-level question: Is this concept related to the "number of sign bits"? If so, should we have a call to ComputeNumSignBits (ValueTracking) somewhere?
