  Hello,

btf::reader::initialize forgets to reset a few data members used
during binary type information loading.  This resetting is key to get
the reader ready for being re-used to load a new binary, like a kernel
module.  Otherwise, the working set just keeps growing unnecessarily.

	* src/abg-btf-reader.cc (btf::reader::initialize): Clear
	types_to_canonicalize_, btf_type_id_to_artifacts_ and cur_tu_.
