Johannes Doerfert 77dbd1d712 [Attributor][NFCI] Manifest assumption attributes explicitly
We had some custom manifest for assumption attributes but we use the
generic manifest logic. If we later decide to curb duplication (of
attributes on the call site and callee), we can do that at a single
location and for all attributes.

The test changes basically add known `llvm.assume` callee information to
the call sites.
