[PATCH v2 07/13] vect: Add EXCLUDE_VIRTUALS argument to _slp_tree::push_vec_def.

This is requried specifically for pushing HSSR loads which not only
define the data loaded, but also do a VDEF to represent the update
to the HSSR state.

gcc/ChangeLog:

	* tree-vect-slp.cc (_slp_tree::push_vec_def): Add exclude_virtuals
	argument.
	* tree-vectorizer.h (_slp_tree::push_vec_def): Ditto.
