Move some basic offset functions to header files for inlining ease Replace enum_pointer_field functions with custom implementations - GC now has custom implementation - other implementations use template<> version Fix misuse of shared_ptr<type_descriptor_t> in various built-in types Observed 5 - 8 % improvement in GC for compiler scenario.
