Dodji Seketeli 1466510881 [PERF] Pass a bunch of perf-sensitive smart pointers by reference
* include/abg-fwd.h (lookup_type_in_corpus, lookup_type_in_scope)
	(lookup_var_decl_in_scope): Pass the decls smart pointers by
	reference.
	* src/abg-ir.cc (lookup_type_in_corpus, lookup_type_in_scope)
	(lookup_var_decl_in_scope): Pass the decls smart pointers by
	reference, for performance reasons.
