[PATCH v1 4/8] vect: Add EXCLUDE_VIRTUALS argument to _slp_tree::push_vec_def.

[Alfie Richards]

This is requried to pushing first faulting reads which not only do a load
but also do a VSET to represent the update to the first fault 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.
