* include/abg-comparison.h
	(diff_category::HARMLESS_SYMBOL_ALIAS_CHANGE_CATEORY): New
	enumerator.
	(diff_category::EVERYTHING_CATEGORY): Adjust.
	* include/abg-ir.h (elf_symbol::get_aliases_id_string)
	(elf_symbol::does_alias, elf_symbols_alias)
	(compute_aliases_for_elf_symbol): Declare new functions ...
	* src/abg-ir.cc (elf_symbol::get_aliases_id_string)
	(elf_symbol::does_alias, elf_symbols_alias)
	(compute_aliases_for_elf_symbol): ... and define them.
	(function_decl::operator==): Take in account elf symbol aliases.
	* src/abg-comp-filter.cc (function_name_changed_but_not_symbol):
	Define new static functions.
	(harmless_filter::visit): Categorize function name changes that
n	doesn't impact underlying elf symbols (or the fact that two
	symbols were aliases and are not anymore) as harmless.
	* src/abg-comparison.cc (function_decl_diff::report): Properly
	report function name changes, or symbol aliases changes for that
	matter.  Also report inline-ness declaration changes.

	function.
	(build_function_decl): Use the above.
