Log:

	* varasm.c (set_implicit_section): New function.
	(resolve_unique_section): Use it to set implicit section
	for aliases, too.
	(get_named_text_section): Use symtab_get_node (decl)->implicit_section
	(default_function_section): Likewise.
	(decl_binds_to_current_def_p): Constify argument.
	* varasm.h (decl_binds_to_current_def_p): Update prototype.
	* asan.c (asan_protect_global): Use symtab_get_node (decl)->implicit_section.
	* symtab.c (dump_symtab_base): Dump implicit sections.
	(verify_symtab_base): Verify sanity of sectoins and comdats.
	(symtab_resolve_alias): Alias share the section of its target.
	(set_section_1): New function.
	(symtab_node::set_section): Move here, recurse to aliases.
	(verify_symtab): Check for duplicated symtab lists.
	* tree-core.h (implicit_section_name_p): Remove.
	* tree-vect-data-refs.c: Include varasm.h.
	(vect_can_force_dr_alignment_p): Fix conditional on when
	decl bints to current definition; use
	symtab_get_node (decl)->implicit_section.
	* cgraph.c (cgraph_make_node_local_1): Fix section set.
	* cgraph.h (struct symtab_node): Add implicit_section.
	(set_section): Rename to ...
	(set_section_for_node): ... this one.
	(set_section): Declare.
	* tree.h (DECL_HAS_IMPLICIT_SECTION_NAME_P): Remove.
	* lto-cgraph.c (lto_output_node, lto_output_varpool_node,
	input_overwrite_node, input_varpool_node): Stream implicit_section.
	* ipa.c (symtab_remove_unreachable_nodes): Do not check symtab before
	removal; it will fail in LTO.
	
	* vtable-class-hierarchy.c: Use symtab_get_node (var_decl)->implicit_section.
	* optimize.c (cdtor_comdat_group): Fix handling of aliases.
	(maybe_clone_body): Move symbol across comdat groups.
	* method.c (use_thunk): Copy implicit section flag.

	* go/go-gcc.cc (Gcc_backend::global_variable_set_init): Use
	symtab_get_node(var_decl)->implicit_section.

	* lto.c (read_cgraph_and_symbols): Remove unreachable symbols.
	(do_whole_program_analysis): Use verify_symtab.
