Nikita Popov 7c0d52ca91 [ValueTracking] Support dominating known bits condition in and/or (#74728) ...

This extends computeKnownBits() support for dominating conditions to
also handle and/or conditions. We'll look through either and or or
depending on which edge we're considering.

This change is mainly for the sake of completeness, so we don't start
missing optimizations if SimplifyCFG decides to merge some branches.
