gimple.c (gimple_canonical_types, [...]): Move to lto/lto.c

2013-10-14  Richard Biener  <rguenther@suse.de>

	* gimple.c (gimple_canonical_types, canonical_type_hash_cache,
	iterative_hash_canonical_type, gimple_canonical_type_hash,
	gimple_canonical_types_compatible_p, gimple_canonical_type_eq,
	gimple_register_canonical_type, print_gimple_types_stats,
	free_gimple_type_tables): Move to lto/lto.c
	(gt-gimple.h): Do not include.
	* gimple.h (gimple_register_canonical_type,
	print_gimple_types_stats, free_gimple_type_tables): Remove.
	* Makefile.in (GTFILES): Remove gimple.c.

	lto/
	* lto-lang.c (lto_init): Do not re-init canonical types here.
	(lto_register_canonical_types): Move to ...
	* lto.c (lto_register_canonical_types): ... here.
	(gimple_canonical_types, canonical_type_hash_cache,
	iterative_hash_canonical_type, gimple_canonical_type_hash,
	gimple_canonical_types_compatible_p, gimple_canonical_type_eq,
	gimple_register_canonical_type): Add canonical type merging machinery
	moved from gimple.c.
	(read_cgraph_and_symbols): Init and free canonical type tables
	here.
	(print_lto_report_1): Report canonical type table stats here.
