Nikita Popov bb7c898cb7 [ValueTracking] Support funnel shifts in computeKnownBits() 
If the shift amount is known, we can determine the known bits of the
output based on the known bits of two inputs.

This is essentially the same functionality as implemented in D54869,
but for ValueTracking rather than InstCombine SimplifyDemandedBits.

Differential Revision: https://reviews.llvm.org/D55140
