Struct vtables store bitmask of unboxed fields
* libguile/struct.h (scm_vtable_index_unboxed_fields): Allocate slot for bitmask of which fields are unboxed. (SCM_VTABLE_FLAG_SIMPLE, SCM_VTABLE_FLAG_SIMPLE_RW): Remove flags. Renumber other flags. (SCM_VTABLE_SIZE, SCM_STRUCT_SIZE): New helpers; long overdue. (SCM_VTABLE_UNBOXED_FIELDS, SCM_VTABLE_FIELD_IS_UNBOXED): (SCM_STRUCT_FIELD_IS_UNBOXED): New macros. * libguile/struct.c (set_vtable_access_fields): Rename from set_vtable_layout_flags, and initialize the unboxed flags bitmask instead of computing vtable flags. (scm_struct_init, scm_c_make_structv, scm_allocate_struct): Simplify. (scm_i_make_vtable_vtable): Adapt. (scm_i_struct_equalp, scm_struct_ref, scm_struct_set_x) (scm_struct_ref_unboxed, scm_struct_set_x_unboxed): Simplify. * libguile/vm-engine.c (VM_VALIDATE_BOXED_STRUCT_FIELD): (VM_VALIDATE_UNBOXED_STRUCT_FIELD): Adapt definitions. (struct-ref, struct-set!, struct-ref/immediate) (struct-set!/immediate): Simplify definitions. * libguile/hash.c (scm_i_struct_hash): Simplify. * libguile/goops.c (scm_sys_clear_fields_x): Simplify. * libguile/foreign-object.c (scm_make_foreign_object_n): (scm_foreign_object_unsigned_ref, scm_foreign_object_unsigned_set_x): Simplify.
