Remove misleading sorting function in ggc memory report.

2019-10-29  Martin Liska  <mliska@suse.cz>

	* cgraphunit.c (symbol_table::compile): Remove argument
	for dump_memory_report.
	* ggc-common.c (dump_ggc_loc_statistics): Likewise.
	(compare_final): Remove in order to make report
	better readable.
	* ggc.h (dump_ggc_loc_statistics):  Remove argument.
	* mem-stats.h (mem_alloc_description::get_list):
	Do not pass cmp.
	(mem_alloc_description::dump): Likewise here.
	* toplev.c (dump_memory_report): Remove final
	argument.
	(finalize): Likewise.
	* toplev.h (dump_memory_report): Remove argument.
2019-10-29  Martin Liska  <mliska@suse.cz>

	* lto.c (do_whole_program_analysis): Remove argument.
