Introduce -fdump-ipa-clones dump output

	* cgraph.c (symbol_table::initialize): Initialize
	ipa_clones_dump_file.
	(cgraph_node::remove): Report to ipa_clones_dump_file.
	* cgraph.h: Add new argument (suffix) to cloning methods.
	* cgraphclones.c (dump_callgraph_transformation): New function.
	(cgraph_node::create_clone): New argument.
	(cgraph_node::create_virtual_clone): Likewise.
	(cgraph_node::create_version_clone): Likewise.
	* dumpfile.c: Add .ipa-clones dump file.
	* dumpfile.h (enum tree_dump_index): Add TDI_clones
	* ipa-inline-transform.c (clone_inlined_nodes): Report operation
	to dump_callgraph_transformation.
