Handwritten part of conversion of passes to C++ classes

gcc/
	* Makefile.in (PASS_MANAGER_H): Add dep on pass-instances.def.
	(toplev.o): Add dep on PASS_MANAGER_H.
	* cgraphunit.c (cgraph_process_new_functions): Rework invocation
	of early local pases to reflect this moving from a global to a
	member of gcc::pass_manager.
	(cgraph_add_new_function): Likewise.
	* lto-cgraph.c (lto_output_node): Update for conversion of
	struct ipa_opt_pass_d to a C++ subclass of opt_pass.
	* passes.c (opt_pass::clone): New.
	(opt_pass::gate): New.
	(opt_pass::execute): New.
	(opt_pass::opt_pass): New.
	(pass_manager::execute_early_local_passes): New.
	(pass_manager::execute_pass_mode_switching): new.
	(finish_optimization_passes): Convert to...
	(pass_manager::finish_optimization_passes): ...this.
	(finish_optimization_passes): Update for conversion of passes to
	C++ classes.
	(register_dump_files_1): Use has_gate since we cannot portably
	check a vtable entry against NULL.
	(dump_one_pass): Likewise.
	(ipa_write_summaries_2): Likewise.
	(ipa_write_optimization_summaries_1): Likewise.
	(ipa_read_summaries_1): Likewise.
	(ipa_read_optimization_summaries_1): Likewise.
	(execute_ipa_stmt_fixups): Likewise.
	(pass_manager::pass_manager): Rewrite pass-creation, invoking
	pass-creation functions rather than wiring up globals, and
	storing the results in fields of pass_manager generated using
	pass-instances.def.
	(pass_manager::dump_profile_report): Update for conversion of
	passes to C++ classes.
	(pass_manager::execute_ipa_summary_passes): Likewise.
	(execute_one_ipa_transform_pass): Likewise.
	(execute_one_pass): Use has_gate and has_execute since we cannot
	portably check a vtable entry against NULL.
	* pass_manager.h (pass_manager::finish_optimization_passes): New.
	(pass_manager): Use pass-instances.def to add fields for the
	various pass instances.
	* toplev.c (finalize): Update for move of
	finish_optimization_passes to a method of gcc::pass_manager.
	* toplev.h (finish_optimization_passes): Move to method of class
	pass_manager.
	* tree-pass.h (struct pass_data): New.
	(opt_pass): Convert to C++ class, make it a subclass of
	pass_data.
	(opt_pass::gate): Convert to virtual function.
	(opt_pass::~opt_pass): New.
	(opt_pass::clone): New.
	(opt_pass::execute): Convert to virtual function.
	(opt_pass::opt_pass): New.
	(opt_pass::ctxt_): new.
	(gimple_opt_pass): Convert to subclass of opt_pass.
	(gimple_opt_pass::gimple_opt_pass): New.
	(rtl_opt_pass): Convert to subclass of opt_pass.
	(rtl_opt_pass::rtl_opt_pass): New.
	(ipa_opt_pass_d): Convert to subclass of opt_pass.
	(ipa_opt_pass_d::ipa_opt_pass_d): New.
	(simple_ipa_opt_pass): Convert to subclass of opt_pass.
	(simple_ipa_opt_pass::simple_ipa_opt_pass): New.
	* config/i386/i386.c (rest_of_handle_insert_vzeroupper): Rework
	invocation of pass_mode_switching to reflect this moving from a
	global to a member of gcc::pass_manager.
	(ix86_option_override): Rework how pass_insert_vzeroupper is
	added to the pass_manager to reflect autogenerated changes.
	* config/i386/t-i386 (i386.o) Add deps on CONTEXT_H and
	PASS_MANAGER_H.

gcc/testsuite/
	* g++.dg/plugin/dumb_plugin.c (plugin_init): Rework how the pass
	is created and added to the pass_manager to reflect
	autogenerated changes.
	* g++.dg/plugin/selfassign.c (plugin_init): Likewise.
	* gcc.dg/plugin/one_time_plugin.c (plugin_init): Likewise.
	* gcc.dg/plugin/selfassign.c (plugin_init): Likewise.
