[AssumeBundles] Add nonnull/align to op bundle if noundef exists

This is a patch to add nonnull and align to assume's operand bundle
only if noundef exists.
Since nonnull and align in fn attr have poison semantics, they should be
paired with noundef or noundef-implying attributes to be immediate UB.
