[PATCH 08/14] ir-priv: Pass shared_ptr parameters by copy to type_topo_comp functor

[Dodji Seketeli]

When looking at some potential data race report, I figured it'd be
better to pass the shared_ptr parameters to the type_topo_comp
functor by value, to avoid potential race conditions when the same
shared_ptr is accessed by several threads at the same time.

	* src/abg-ir-priv.h (type_topo_comp::operator()): Pass parameters
	by value.
