Noah Goldstein 678f32ab66 [ValueTracking] Add more conditions in to isTruePredicate ...

There is one notable "regression". This patch replaces the bespoke `or
disjoint` logic we a direct match. This means we fail some
simplification during `instsimplify`.
All the cases we fail in `instsimplify` we do handle in `instcombine`
as we add `disjoint` flags.

Other than that, just some basic cases.
