Craig Topper dc461c9a16 [ValueTracking] Use KnownOnes to provide a better bound on known zeros for ctlz/cttz intrinics 
This patch uses KnownOnes of the input of ctlz/cttz to bound the value that can be returned from these intrinsics. This makes these intrinsics more similar to the handling for ctpop which already uses known bits to produce a similar bound.
