Nikita Popov dfb369399d [ValueTracking] Directly use KnownBits shift functions 
Make ValueTracking directly call the KnownBits shift helpers, which
provides more precise results.

Unfortunately, ValueTracking has a special case where sometimes we
determine non-zero shift amounts using isKnownNonZero(). I have my
doubts about the usefulness of that special-case (it is only tested
in a single unit test), but I've reproduced the special-case via an
extra parameter to the KnownBits methods.
