Canonicalize function types when reading from DWARF

Up until now, only function types pointed to by a pointer to function
was canonicalized.  This patch also canonicalizes function types that
are used as types for function declarations.

	* src/abg-dwarf-reader.cc (build_function_decl): Canonicalize
	function types.
