class.c (fixup_type_variants): Do not copy TYPE_METHODS
* class.c (fixup_type_variants): Do not copy TYPE_METHODS
(one_inheriting_sig): Assert tat we always set TYPE_METHODS of main variant.
* semantics.c (finish_member_declaration): Likewise.
* method.c (lazily_declare_fn): Allways add method to main variant list.
* dwarf2out.c (gen_member_die): Sanity check that we access TYPE_MAIN_VARIANT
for TYPE_METHODS.
* function.c (use_register_for_decl): Look for TYPE_MAIN_VARIANT when checking
TYPE_METHODS.
* tree.c (free_lang_data_in_type): See TYPE_METHODS to error_mark_node
if non-null.
(build_distinct_type_copy): Clear TYPE_METHODS.
(verify_type_variant): Verify that TYPE_METHODS is NULL for variants.
(verify_type): Allow TYPE_METHODS to be error_mark_node.
* tree.def: Update docs of YTPE_STUB_DECL and TYPE_METHODS.
