Buitlins from AMD's device-libs are compiled without specifying a target-cpu, which results in builtins without the target-features attribute set. Before this patch, when linking this builtins with -mlink-builtin-bitcode the target-features were not propagated in the incoming builtins. With this patch, the default target features are propagated if they are compatible with the target-features in the incoming builtin.
