Changes from v15: * Rebased on top of trunk * Fixed build_invoke * Implemented object_type_p & referenceable_type_p * Prefixed all built-in traits with __builtin instead of __ -- This patch series implements __is_const, __is_volatile, __is_pointer, and __is_unbounded_array built-in traits, which were isolated from my previous patch series "Optimize type traits compilation performance" because they contained performance regression. I confirmed that this patch series does not cause any performance regression. The main reason of the performance regression were the exhaustiveness of the benchmarks and the instability of the benchmark results. Also, this patch series includes built-ins for add_pointer, remove_extent, remove_all_extents, add_lvalue_reference, add_rvalue_reference, decay, rank, is_invocable, and is_nothrow_invocable.
