XML writer: adjust tracking of emitted declarations

Replace the std::unordered_map used to track emitted declarations with a
std::unordered_set as the map only ever held "true". The container
itself does not need to be marked mutable because record_decl_as_emitted
is called in a non-const context and can itself be made non-const. In
addition, the method decl_is_emitted calls a helper which no longer used
anywhere else and can be inlined. The remaining two methods are always
called on non-type declarations, so the test that existed in
decl_is_emitted can be dropped.

	* abg-writer.cc (write_context): Replace mutable
	m_emitted_decls_map with plain m_emitted_decls_set.
	(decl_name_is_emitted): Inlined into decl_is_emitted; dropped.
	(decl_is_emitted): Turn the is_type check into an assert and
	inline decl_name_is_emitted. Look up in set instead of map.
	(record_decl_as_emitted): Make non-const. Insert into set
	instead of map.
