Struct instances now point directly to low level type.

This change eliminates numerous cast expressions and a pointer
chase from some operations, though some, like the struct_type
function, end up chasing an extra pointer.

* struct.c (struct struct_type): New member, self.
(struct struct_inst): Type member changed from val to
struct struct_type *.
(make_struct_type): Initialize new self member.
(super): Obtain type from si->type->self rather than
si->type. There appears to be a bug here.
(make_struct, lazy_struct_init): Initialize type field with
struct pointer rather than type object. Add an assertion which
references the type parameter, to prevent the cobj call from
garbage collecting type.
(copy_struct, clear_struct, replace_struct, reset_struct,
(lookup_slot, slot, slotset, struct_type, uslot_fun,
umethod_fun, struct_inst_print, struct_inst_mark,
struct_inst_equal, struct_inst_hash, struct_inst_equalsub):
All updated to new way of referencing type structure
and type object.
